mdFlow

A fast, lightweight markdown editor built with Tauri 2 + Rust and a plain-TypeScript frontend. Bugter is an IDE-style workspace for markdown: a file explorer, split windows, a command palette, rich preview (mermaid, math, raw HTML), a built-in AI panel, a PDF reader, editable Excalidraw and mindmap boards, and document export.

Editor

• CodeMirror 6 with markdown highlighting, soft-wrap, line numbers, and per-document undo. Markdown tabs include a formatting toolbar; standalone HTML tabs use proper HTML syntax highlighting. Live preview has a 300 ms debounce

Native multi-window

• create independent macOS windows from View or the Dock; each has its own tabs, Explorer workspace, AI panel, and optional Main/Sub split.

Main/Sub split

• each native window can show Main and Sub document panes with independent tabs and type-aware view modes.

Recovery & version history

• unsaved edits are continuously drafted in the background and offered back after a crash or quit (restore / discard banner on launch), without changing the explicit-save model. Bugter detects when an open file changes on disk (reload when clean, conflict prompt when dirty, overwrite protection on save) and keeps per-file local snapshots on save plus manual snapshots, browsable in a version-history panel with Compare and Restore
