Scratch v0.8.0

What's New

Syntax Highlighting & Mermaid Diagrams

• Code blocks now feature syntax highlighting for 20 languages with a GitHub-inspired color scheme
• Select a language from the dropdown or type it after the opening backticks
• Mermaid diagram blocks render live SVG previews with an Edit/Preview toggle
• Diagrams automatically inherit your app's theme colors

KaTeX Math Support

• Write LaTeX math expressions with full KaTeX rendering
• Use $$...$$ for display-style block equations
• Click any rendered expression to edit it in a popup editor

Ollama AI Editing

• Added Ollama as an AI editing provider alongside Claude and Codex
• Run local LLMs for AI-assisted editing without sending data to the cloud
• Select your preferred Ollama model directly from the command palette

Drag-to-Resize Editor Width

• Drag the editor margins to resize the page width in real time
• Your preferred width is saved per session

Save Previewed Notes to Folder

• When you open a note in preview mode (e.g. drag a file in or use "Open With Scratch"), you now have an option to save it to your notes folder

Bug Fixes

• Fixed console window flash on Windows — git and CLI commands no longer briefly show a console window
• Fixed double-window issue on Windows — app no longer opens two windows on startup
• Fixed close window shortcut on Windows — Ctrl+W now correctly closes the window
• Fixed hidden filenames — notes starting with . are now handled correctly
• Fixed mise path resolution — improved PATH detection for mise-managed tool installations
• Improved security practices across the codebase
