🚀 Features

• Introduced a fullscreen slideshow viewer for Markdown documents, complete with pagination controls and seamless document activation.

🐛 Bug Fixes

• Fixed a backward compatibility issue where legacy cache paths caused workspace tab groups to be lost upon restart.

🐛 Bug Fixes

• Resolved an issue where tab groups leaked across different workspaces; tab groups are now correctly isolated and persisted per workspace.

✨ Improvements

• Implemented interactive hover highlights for Markdown tables and accordion (<details>) blocks, ensuring the code editor synchronously highlights the exact source lines corresponding to the UI element.

🐛 Bug Fixes

• Resolved a backwards-compatibility issue during workspace switching where tab states (pins and groups) saved in older versions were discarded and appeared lost upon restoration.

🚀 Features

• Introduced the global Command Palette (accessible via Cmd+Shift+P / Ctrl+Shift+P), providing unified access to application commands with a fuzzy-search interface.

✨ Improvements

• Enhanced command palette usability with dynamic height adjustment, window resizing support, and automatic focus tracking to keep the active selection visible.
• Increased overall rendering stability by ensuring text with script-like characters gracefully falls back to plain text instead of triggering false-positive rendering errors.

🔧 System

• Increased 100% UI localization compliance across all 10 supported languages by integrating translation parameters into deep workspace and file-operation dialogs.

🚀 Features

• Introduced a realtime "Problems Panel", allowing users to quickly identify and navigate to Markdown authoring issues without leaving the editor canvas.
• Added foundational local Markdown diagnostics, currently catching skipped heading levels and broken relative links, which are calculated in the background when documents are opened or saved.

🚀 Features

• Introduced an integrated in-document search feature. Users can now search for specific text within the active Markdown file using the search bar embedded in the ViewModeBar, complete with hit counts and jumping between matches.
• Added comprehensive keyboard navigation for the new document search. Pressing the ArrowUp or ArrowDown keys while focused in the search input quickly jumps to the previous or next match.

✨ Improvements

• Silenced internal testing framework CLI noise to greatly improve developer application stability and reduce memory consumption during test cycles.

🐛 Bug Fixes

• Fixed a crash that occurred when searching for specific multi-byte Japanese characters due to invalid character boundaries.
• Repaired regression on scroll synchronization. Searching and navigating through document matches will now consistently scroll both the editor and preview panels to highlight the correct position.

🐛 Bug Fixes

• Fixed an issue where diagram cache files were not properly cleared from persistent storage.
• Resolved missing localization keys for the new Tab Groups feature across multiple languages.
• Polished Tab Group UI layouts and resolved various internal linter warnings.

🚀 Features

• Introduced the "Tab Groups" feature, allowing users to visually organize and consolidate multiple tabs. Groups can be assigned custom names and colors (from a curated palette of 7), and can be fully collapsed to maximize the editor screen area.
• Enhanced accident prevention safeguards for "Pinned" tabs. Pinned files are now fully protected from bulk-close operations such as "Close Others" or "Close All".

✨ Improvements

• Upgraded the workspace tab restoration (session persistence) logic on application restart, ensuring that advanced states such as tab group affiliations and pinned statuses are seamlessly retained across sessions.

✨ Improvements

• Ensured that diagram previews immediately reflect theme and color changes without requiring an application restart.
• Prevented rendering glitches where outdated cached diagrams in the previous color scheme would incorrectly display after switching themes.

✨ Improvements

• Stabilized UI responsiveness and reduced disk I/O load during typing or frequent file navigation by restructuring the persistent caching strategy.

🚀 Features

• Introduced a permanent Activity Rail on the left side of the workspace, consolidating the workspace toggle, search modal, and recently opened workspaces into a unified navigation bar.
• Added a new "Flat View" mode for the workspace tree, displaying all files in a single list with workspace-relative paths, bypassing deeply nested directory structures.
• Implemented natural sort algorithm across both Tree and Flat views to ensure versioned directories and files (e.g., v0-9 vs v0-11) are ordered intuitively by humans.

✨ Improvements

• Supported drag-and-drop reordering for icons within the Activity Rail, naturally persisting layout preferences to user settings.
• Rearranged the workspace header layout based on user feedback to prioritize readability and group action icons (Expand All, Collapse All, Refresh, Filter) more logically.

✨ Improvements

• Stabilized synchronization between the editor and preview panels to prevent jittering during scroll, particularly at the bottom of long documents and in documents without headings.

✨ Improvements

• Optimized the rendering flow when files are updated from external editors, reducing unnecessary flickering in the preview and applying updates faster.
• Improved nested task lists formatting by allowing the entire row to be clicked to toggle checks.

🐛 Bug Fixes

• Resolved a visual bug where multiple lines would highlight simultaneously on hover; the highlight is now precisely constrained to the row under the cursor.

🐛 Bug Fixes

• Completely resolved the issue with Homebrew auto-updater conflicts. The application will now securely untap and detach itself from Homebrew package management silently in the background simply by launching the KatanA app normally.

🐛 Bug Fixes
