Window Spaces — Obsidian Plugin

💡 The Philosophy: Free Your Main Workspace

Obsidian’s vibrant plugin ecosystem and flexible layouts make it the ultimate "Everything Notebook". But as our vaults grow, so does the clutter:

• 🗂️ The Overcrowded Main Window: Canvas whiteboards, Excalidraw sketches, Dataview dashboards, graph views, and complex note splits all compete for the exact same screen real estate.
• ⚡ Context Switching Overhead: Switching between project management, deep literature research, and daily task review constantly disrupts your open tabs, sidebars, and pane splits.
• 🖥️ Underutilized Multi-Monitors: Modern workstations feature multiple displays, yet managing distinct, persistent layouts across separate windows is difficult.

Window Spaces is an organic, seamless extension of Obsidian. Instead of cramming everything into a single main window, Window Spaces lets you isolate distinct workflows into dedicated Popout Work Cabins (Spaces).

With focus interception technology, popout activity bar engines, and per-window layout lifecycle management, your heavy plugins, complex splits, and research setups effortlessly transition into independent windows — letting you focus on one task at a time with zero clutter.

⚖️ Obsidian Core Workspaces vs. Window Spaces

Feature	Obsidian Native Workspaces	Window Spaces
Scope of Layout	Global (replaces main window & all splits)	Per-Window (isolates independent popout cabins)
Popout Sidebar & Activity Bar	❌ None (bare popout windows only)	✅ Full Native-like Left & Right Activity Bars
Visual Window Identity	❌ Generic, indistinguishable windows	✅ 4-Side Accent Frames, Logos, & Status Badges
Filesystem Context Isolation	❌ Shows full vault file tree	✅ Pairs with Folder Spaces for directory scoping
File Routing Protection	None; tabs and views across main/popout windows interfere with each other	✅ Window-Locked Routing: Routes file opens to center editor; core views (Outline, Backlinks) & community views (Grid Explorer) co-exist as independent multi-instances without interference
Dual Layout Collapse Guardrails	❌ Closing the last tab destroys container and breaks split layout	✅ Dual Guardrails: Closing last central tab converts in-place to New Tab; sidebar last tab deletion prevention
Auto-Save Granularity	Manual snapshot only	✅ Per-Space Auto-Save (5s debounce + close snapshot)
Multi-Monitor Geometry	Prone to multi-DPI shifts	✅ Pixel-precise restoration with off-screen protection

✨ Key Features & Recent Highlights

🪟 1. Popout Activity Bar & Sidebar Engine (New in v1.1+)

Obsidian popout windows natively lack sidebars. Window Spaces injects a true, native-like Activity Bar & Collapsible Sidebar engine directly into popout windows:

• Collapsible Sidebars: Toggle left/right sidebars using native-styled toolbar buttons or customizable hotkeys.
• Right-Click Context Menu: Right-click directly on any Activity Bar icon to toggle view visibility, switch sidebars, or hide/show the activity bar and sidebar.
• Dynamic View Discovery & Prewarming: Embed File Explorer, Bookmarks, Search, Outline, or third-party views directly in popouts.
• Ultra-Smooth Sidebar Resizing: Uses exact borderBoxSize measurements with a 1px change-threshold guard to eliminate sidebar jitter, bounce-back, and slow border shrinkage.
• Drag-to-Reorder & One-Click Import in Settings: Rearrange popout activity bar buttons with intuitive drag-and-drop, and import your current main window sidebar layout with a single click; resetting settings safely preserves your saved spaces.

🚀 2. Folder Spaces Synergy: Scoped Project Cabins

Pair Window Spaces with Folder Spaces to achieve Double Context Isolation:

• Window Isolation: Window Spaces isolates the window lifecycle, multi-monitor position, popout activity bars, and accent frame themes.
• Filesystem Scoping: Dock a Folder Space Explorer in the popout sidebar, locking the visible file tree strictly to a specific project subfolder (e.g. Projects/Apollo/).
• Smart Leaf Routing: Clicking any file inside the scoped explorer routes directly into the popout's central editor without disturbing the sidebar structure.
• Micro-Vault Experience: Work in an isolated project cabin with zero visual clutter from the rest of your vault.

🎨 3. Visual Identity & Accent Window Frames (New in v1.1+)

Never lose track of your open cabins across multiple displays:

• 4-Side Perimeter Accent Frame: Highlights the window border with your Space's theme color (automatically hides when maximized for a seamless edge-to-edge view).
• Custom Logos & Corner Folds: Assign any Emoji or Lucide icon, paired with folded corner accents.
• Status Bar Badge: Displays the active space name and quick-save status at the bottom of the popout.
• Atmospheric Accents: Subtle theme glows on pane splitters and soft background tints on activity bars.

🎯 4. Window-Locked Routing & Dual Layout Guardrails (New in v1.2+)

Obsidian's architecture is natively designed around a single main window. Opening an Outline, Backlinks, or community views (such as Grid Explorer or Notebook Navigator) in a popout window frequently causes views to jump back to the main window, steal focus, or overwrite each other due to global getLeavesOfType lookups. Window Spaces introduces Window-Locked Routing & Deep Leaf Interception, paired with comprehensive layout collapse defenses:

• Multi-Instance Concurrency for Core & Community Views: Breaks Obsidian's singleton limitations. Native core views (Outline, Backlinks, Tags, Search, Bookmarks) and community plugin views (e.g. Grid Explorer, Notebook Navigator) can now co-exist as multiple independent instances across different windows simultaneously without stealing focus or colliding.
• Per-Window Event Gating & Active File Tracking: Intercepts file-open event broadcasts and workspace.getActiveFile(). An Outline in Window A strictly tracks the note active in Window A, while an Outline in Window B tracks Window B — completely eliminating cross-window context bleeding.
• Dual Layout Collapse Guardrails:
  • In-Place New Tab Conversion: When closing the last remaining tab in the central content area, Window Spaces intercepts detach and converts the view in-place into an Obsidian native New Tab (empty view), preventing container destruction and split collapse.
  • Sidebar Tab Protection: Attempting to close the sole remaining tab in a popout sidebar is cleanly blocked with a native notice ("The last tab in the sidebar cannot be closed"), safeguarding the sidebar container.
• Non-Navigable & Pinned Tab Safe Routing: When the active center leaf contains a non-navigable view (e.g., Outline, Canvas, Graph) or a pinned tab, clicking a file from the sidebar automatically opens a new tab in the central area rather than failing navigation or overwriting the view.
• Layout Structure Guardrails: Drop boundaries prevent tabs from accidentally breaking activity bars; missing or renamed files are safely held by native empty tab placeholders.

⚡ 5. Zero-Flicker Restore & Multi-Monitor Geometry (New in v1.2+)

• Target-Only Reconcile: Restoring or updating a space only updates the target window without jittering or flickering other open windows.
• Geometry Pre-positioning: Remembers exact window coordinates and sizes across multiple monitors.
• Off-Screen Guard: Automatically recalculates coordinates if an external monitor was disconnected.
• Startup Auto-Matching: Automatically detects and re-links existing popout windows upon Obsidian restart.

🔄 6. Per-Space Auto-Save

• Effortless Synchronization: Toggle 🔄 Auto-save on any Space. Modifications made during your work session are automatically saved in the background with a 5-second debounce and an instant snapshot on window close.
• Template Safety: Keep auto-save disabled on standard template spaces to prevent accidental layout drift.

🗂️ 7. Unified 3-in-1 Interface & Section Groups

• Flexible Mount Points: Access your Spaces seamlessly from the Left/Right Sidebar, as an Editor Tab, or via the Quick-Popup Modal (Ribbon Icon or Hotkeys).
• Section Groups & Archiving: Organize your spaces into collapsible sections, drag to reorder, and archive inactive spaces (📦 Archived).
• Hover Content Preview: Hover over any Space to instantly preview its included files, active tab, and pinned document structure.
