4D Eisenhower Matrix — Obsidian plugin

Visualize tasks across your entire vault in a 5-quadrant Eisenhower matrix (DO / DECIDE / DELEGATE / DELETE / OPEN) + Kanban view. Reads and writes Obsidian Tasks syntax — #tags, 📅 due, 🛫 start, ✅ done, priority.

A morning dashboard for deciding what to do now: open it, see tasks split by priority, check off the done ones, add new ones. Markdown files stay the source of truth — the plugin is just a visual layer on top.

Features

Feature	What it does
5-quadrant matrix	DO / DECIDE / DELEGATE / DELETE plus a catch-all OPEN. The quadrant is the first #tag after the checkbox (#DO, #DECIDE, #DELEGATE, #DELETE); anything else lands in OPEN.
Kanban view	Expand any quadrant to full width with To-do · In progress · Scheduled · Done status columns. On desktop drag cards between columns to change status, onto another quadrant to move them, or add a task straight into a column. On mobile/tablet the board scrolls horizontally and you change status via the card menu (Mark as…).
Cross-vault aggregation	Collects tasks from every .md file in the vault (Dataview-like), not just today's daily note — one board for your whole second brain.
6 task statuses	Things-style [ ] to-do · [/] in progress · [x] done · [-] canceled · [>] forwarded · [<] scheduling. Each card shows a status box; set any state via right-click → Mark as….
Full CRUD	Add (text + tags + due date + priority), edit inline, toggle done, move between quadrants — every change is written straight back to your Markdown.
Priority	Obsidian Tasks convention: 🔺 highest · ⏫ high · 🔼 medium · 🔽 low · ⏬ lowest. It's also the manual lever for ordering — raise a priority and the task jumps up.
Due / start / done dates	Reads and writes 📅 due, 🛫 start, ✅ done. Overdue tasks are highlighted and float to the top of their quadrant.
Markdown in task text	Inline bold, italic, code, strikethrough; a leading #…###### renders the task as a heading.
Clickable links	[[wikilinks]] (with #heading / |alias) and [text](url) in the task title are live — click to open the note (resolved relative to the task's file) or the URL; Ctrl/Cmd-click opens in a new pane. Clicks don't trigger drag or edit. Only https:/http:/mailto: URLs open externally — other schemes stay plain text.
Tag autocomplete	Suggests existing vault tags as you type, so you don't create near-duplicates.
Filter by tag	Context-tag chips in the filter bar (multi-select, OR logic) + a virtual "Other" chip for untagged tasks.
Due-date quick filters	Today (overdue + due today), Selected (due exactly on the date picked in the header), and This week (overdue + next 7 days) buttons at the start of the filter bar, set apart in orange.
Date navigation	← / → / calendar / Today, plus a day-cutoff banner offering to jump to today after midnight.
Undo grace period	A 3-second window with a green countdown bar after you complete or cancel a task — click again to undo.
Compact mode	Header toggle that shrinks every card to two lines (text + priority/due date) for a denser overview.
Show / hide done	The "Done" toggle reveals or hides finished tasks ([x] + [-]); the task counter follows the toggle.
Collapsible UI	Collapse individual quadrants or the whole header to free up space — handy on mobile.
Deterministic sorting	Within a quadrant: overdue → priority → due date → alphabetical. No accidental drag-reordering.
Daily note integration	New tasks go under a configurable section heading; if today's daily note is missing it's created automatically, honoring your core "Daily notes" template ({{date}}, {{title}}, {{time}}).
Excluded folders	Point the matrix away from templates, archives or anything you don't want scanned.
Desktop & mobile	Works on desktop and Android (isDesktopOnly: false); responsive layout with touch-friendly controls.
Theme-aware	Built entirely on Obsidian CSS variables, so it adapts to your light/dark theme and accent colour.

Installation

Settings → Community plugins → Browse → search "4D Eisenhower Matrix" → Install → Enable.

Then open it via the ribbon icon (grid, in the left sidebar) or the command palette → Open matrix.

Task syntax

The plugin reads/writes standard Obsidian Tasks syntax:

- [ ] #DO #Personal ⏫ 📅 2026-05-20 🛫 2026-05-15 Important call with Alice
- [x] #DECIDE Long-term planning ✅ 2026-05-10
- [ ] task without a quadrant tag  ← lands in the OPEN quadrant

Quadrant tags (the first token after - [ ]):

Tag	Quadrant	Meaning
#DO	🔴 DO	Important + Urgent
#DECIDE	🔵 DECIDE	Important + Less Urgent
#DELEGATE	🟢 DELEGATE	Less Important + Urgent
#DELETE	🟡 DELETE	Less Important + Less Urgent
(other / none)	⚫ OPEN	Uncategorized

Priority (Obsidian Tasks convention):

Emoji	Level
🔺	Highest
⏫	High
🔼	Medium
🔽	Low
⏬	Lowest

Controls

Action	How
Toggle a task	Click the checkbox · 3 s grace period (click again to undo)
Add a task	Click + in the quadrant header → text + #tags + 📅 + ⏫ → Enter
Edit a task	Desktop: double-click the card. Mobile: long-press / double-tap → menu → Edit
Change due date alone	Click the 📅 badge on the card
Move between quadrants	Desktop: drag the card onto the target quadrant. Mobile: long-press / double-tap → menu → "Move to…"
Open the source file	Desktop: right-click the card. Mobile: long-press / double-tap. → menu (current pane / new tab / split / window) — the cursor lands on the task's line
Filter by tag	Click a chip in the filter bar (multi-select, OR)
Due-date quick filter	The Today (overdue + due today) / Selected (due on the date picked in the header) / This week (overdue + next 7 days) buttons at the start of the filter bar
Previous / next day	The ← → arrows in the header, the calendar, or "Today"
Collapse a quadrant	Click the ▼/▶ arrow next to the quadrant name
Collapse the whole header	The ▲ button top-right (handy on mobile)
Show completed tasks	The "Done" toggle in the header
Compact view	The "Compact" toggle in the header — 2-line cards

Kanban view	Click the kanban icon in a quadrant header → status columns; click it again to return to the grid. On mobile/tablet the columns scroll horizontally; change a card's status via its menu (Mark as…)

In-quadrant order

Deterministic — cannot be reordered manually:

1. Overdue (📅 < today) — at the top
2. Priority desc — 🔺 → ⏫ → 🔼 → 🔽 → ⏬ → no priority
3. Due date asc — nearest deadline first
4. Alphabetical by text

The manual lever for reordering is priority — set it and the task jumps up.

Settings

Settings → 4D Eisenhower Matrix:

• Daily folder — where new daily notes are created. Empty = respect the core "Daily notes" plugin config. Override = a custom path (with a folder suggester).
• Daily section heading — the heading in the daily note under which today's tasks are read and added. Default: # Today. Set it to whatever you use (e.g. # Dnes, ## Tasks).
• Excluded folders — tasks from these folders are ignored. Default: none — add the folders you want excluded yourself. UI with + / × buttons and a folder suggester.

Daily note integration

The plugin looks for a configurable section heading in the daily note (set via Settings → Daily section heading, default # Today). New tasks are inserted under that heading.

If a daily note for the given day doesn't exist and you add the first task, the plugin creates it automatically:

1. If the core "Daily notes" plugin has a template configured, it uses that (expanding {{date}}, {{title}}, {{time}}).
2. Otherwise it falls back to a minimal scaffold (frontmatter + the configured section heading).

Mobile

Works on Android (isDesktopOnly: false; iOS untested but should work).

• Long-press or double-tap a card → context menu (Edit · Open file · Move to…)
• Moving between quadrants on mobile is done via the menu ("Move → DECIDE" etc.). Touch-drag is unreliable inside the Obsidian mobile webview, so the menu is used instead — two taps, deterministic.
• Collapsed header (the ▲ button) — frees up vertical space for the matrix.

Roadmap

• Quick-add task via the Command Palette (without opening the view)
• Keyboard shortcuts inside the view (J/K navigation, X toggle, N new task)
• Full moment.js syntax in daily templates (currently only {{date}} / {{title}} / {{time}})

Known limitations

• Manual ordering across files (one task in a daily note, another in a project) is not supported — the sort is deterministic.

Changelog

1.0.27 — Security hardening + cleanup after a code audit: external links in task titles are now restricted to https: / http: / mailto: — anything else (file:, javascript:, data:, …) renders as plain text and never opens (checked both at render time and again at open time). Also, tasks with empty text (e.g. a lone - [ ] #DO line) are now hidden from the matrix consistently — previously they showed as "(empty text)" cards when they came from the daily note.

Earlier versions

• 1.0.26 — Task titles now render clickable links: [[wikilinks]] (including #heading and |alias forms) and [text](url). Internal links open the note resolved relative to the task's own file; external URLs open in the browser; Ctrl/Cmd-click opens in a new pane. Clicking a link doesn't start a drag or open the editor, so drag-to-move still works. (Requested by Ampa — thanks!)

• 1.0.25 — Fixed the date picker jumping by a whole month: navigating months in the calendar (the ↑/↓ arrows) no longer commits the date prematurely — it just shows the next/previous month so you can click the exact day. The native picker's month-navigation input events were being treated as a final selection; the picker now commits only on the real change (day click). Applies to the header date navigation and every due-date badge.

• 1.0.24 — Added a Selected due-date quick filter (between Today and This week): shows tasks due exactly on the date currently picked in the header bar — no overdue, just that one day. Follows the date picker live.

• 1.0.23 — Changed the default Daily section heading from # Dnes to # Today. Only affects fresh installs / users who never set their own — existing configurations keep their value.

• 1.0.22 — Kanban view is now available on mobile and tablet, not just desktop. The status columns scroll horizontally (swipe between them); since touch-drag is unreliable in the Obsidian mobile webview, you change a card's status through its menu (Mark as…) — the card jumps to the matching column.

• 1.0.21 — Lint cleanup for the store review: void-wrapped the async event handlers, switched to activeDocument / activeWindow for popout-window compatibility, removed a redundant type assertion, and described the remaining directive comment. No user-facing changes. (Three deprecation recommendations are left as-is — their replacements aren't available at minAppVersion 1.8.0.)

• 1.0.20 — Store-compliance fixes flagged by Obsidian's automated review: raised minAppVersion to 1.8.0 (the plugin uses newer vault/workspace APIs), documented the two eslint-disable directives, and made onunload synchronous.

• 1.0.19 — Refined the due-filter chips: the selected one now stands out clearly (orange fill + border) while the unselected one is distinguished by orange text only.

• 1.0.18 — Due-date quick filters: Today (overdue + due today) and This week (overdue + next 7 days) buttons at the start of the filter bar, set apart in orange.

• 1.0.13–1.0.17 — Kanban view (desktop): per-quadrant toggle into To-do / In progress / Scheduled / Done status columns, drag to change status or move quadrant, add tasks per column, "Back to grid" button.

• 1.0.7–1.0.12 — Six Things-style task statuses with a custom status box, Markdown headings in task text, half-square "in progress" icon, view controls kept in the collapsed header.

• 1.0.6 — Inline Markdown in task text + compact 2-line card mode.

• 1.0.0 — First release: 5-quadrant matrix, cross-vault aggregation, CRUD, priority, tag autocomplete, filters, dates, grace period, daily-note integration.
