Added

• Styled keybinding hints footer - New context-aware footer bar showing relevant keybindings

  • Styled key badges with theme colors (help_key_bg, help_key_fg, help_desc_fg, footer_bg)
  • Hints update based on current mode (Normal, Interactive, LinkFollow, DocSearch, etc.)
  • Element-specific hints in interactive mode (Checkbox, Table, Link, Details, CodeBlock, Image)
  • Table mode shows cell navigation hints (j/k Row, h/l Col, e Edit, y Copy)

• Vim-style count prefixes - Repeat motions with numeric prefixes like vim

  • 5j moves down 5 items, 10k moves up 10 items
  • Works in Normal mode (outline/content navigation) and Interactive mode
  • Supports: j/k navigation, h/l table columns, content scrolling
  • 0 without count goes to first item (vim behavior preserved)
  • Link follow mode still uses 1-9 for direct link jumping

• Collapse/Expand commands - New command palette commands for outline management

  • :collapse / :ca - Collapse all headings with children
  • :expand / :ea - Expand all headings
  • :collapse N - Collapse all headings at level N (e.g., :collapse 2 for h2)
  • :expand N - Expand all headings at level N
  • Status messages show count of affected headings

• Inline HTML tag rendering - Parse HTML tags in details block summaries

  • <strong>, <b> render as bold
  • <em>, <i> render as italic
  • <code> renders as inline code
  • No longer shows literal <strong> tags in rendered view

• Nested interactive elements in details blocks - Select elements inside expanded details

  • Tables, links, code blocks, images inside details are now selectable
  • Hierarchical status display: ▸Navigation > Table: 5×3
  • Expansion state persists after exiting interactive mode

• Safe edit buffer system - Table cell edits are now buffered in memory instead of immediately written to file

  • Changes are applied to in-memory document for immediate display
  • Explicit save required with :w command to write changes to disk
  • Status shows "X unsaved change(s)" after edits
  • Prevents accidental data loss from unforeseen bugs

• Save command (:w) - New command to save pending edits

  • :w, :write, or :save writes all buffered edits to file atomically
  • Shows confirmation: "Saved X change(s) to filename.md"

• Undo command (:u and Ctrl+z) - Undo table cell edits before saving

  • :u or :undo in command palette undoes last edit
  • Ctrl+z keybinding in Interactive and InteractiveTable modes
  • Stack-based undo: each edit can be individually reverted
  • Shows remaining unsaved changes count after undo

• Quit confirmation for unsaved changes - Prompts before quitting with unsaved edits

  • Dialog shows number of unsaved changes
  • Enter/y saves changes and quits
  • Escape cancels and returns to normal mode

Changed

• Status bar shows context-aware position - Position info based on focused pane

  • Outline focused: [Outline] 3/15 (20%) - heading position
  • Content focused: [Content] Line 42 (35%) - scroll position
  • Cleaner status bar without inline keybinding hints (moved to footer)

• Esc key behavior in normal mode - Shows helpful hint instead of doing nothing

  • Displays: "Press q to quit • : for commands • ? for help"
  • Guides new users on how to exit or access features

Fixed

• Table navigation in interactive mode - j/k now moves cells when in table mode

  • Previously j/k moved between elements instead of table rows
  • Esc now exits table mode before exiting interactive mode
