Features

• Opens .opml files in a dedicated tree-view editor
• Expand/collapse outline nodes with a single click
• Double-click any node to edit its text label in-place
• Right-click context menu: add child, add sibling, delete node
• Drag-and-drop to reorder nodes
• Click a node to inspect and edit its attributes (type, xmlUrl, htmlUrl, and any custom attributes) in a panel below the tree
• Toggle to raw XML view for direct editing
• Auto-saves with configurable debounce delay
• Cmd+S / Ctrl+S manual save
• Adapts to any Obsidian theme (uses CSS variables throughout)
