Show images in asset directories with preview, rename, replacement, and trash recovery. Update local Markdown references when images move and restore original files if related metadata cannot be committed.
Refresh image previews after replacement and compare actual contents when deduplicating subsequent uploads.
- WebCrypto keyring (PBKDF2 600k + AES-GCM master key) and per-note/per-image keys
- Encrypt/decrypt commands convert the note and its own images, deleting the originals
- Unlock, setup and change-password dialogs; manual lock; lock on page close
- Encrypted images are decrypted to blob URLs; pasted images are encrypted before upload
- Rewrite image links in the browser when renaming an encrypted note
- Skip local drafts for encrypted notes and confirm before closing with unsaved changes
- Show encrypted notes as locked with an explanation outside secure contexts
- Parser extensions shared by the editor and the HTML renderer: ==highlight==, $inline math$
(Pandoc rules, so amounts like $5 are not math), $$ math blocks, footnote references and
definitions, [TOC], and YAML front matter
- Live preview: highlight, superscript/subscript, emoji names (gemoji), footnote references
with the definition as tooltip, a clickable table of contents, styled front matter
- Math (KaTeX) and Mermaid render in place; while editing a block the source is shown with a
live preview below. KaTeX, Mermaid and the emoji table are loaded only when a note uses them
- KaTeX is pinned to 0.18 so Mermaid shares the same copy
- Move editor focus tracking out of table.ts so block widgets and tables use the same state
- Copy button in the top-right of fenced code blocks, with execCommand
fallback when the Clipboard API is unavailable over plain HTTP
- Mod-A inside a code block selects the block content first; pressing
it again selects the whole document
- Paint code block backgrounds on a ::before layer below CodeMirror's
selection layer so selections inside code blocks are visible
- Table toolbar sits in reserved space above the table instead of
overlapping it, with grouped icon buttons
- Top-level GFM tables render as an editable widget: click a cell to
edit its Markdown source, Tab/Enter/arrows to navigate, toolbar to
insert/delete rows and columns or switch to source
- Structural table edits are isolated undo steps; focus is restored
after the widget is rebuilt
- Clicking an image moves the cursor to its syntax to reveal the source
- Renderer escapes raw HTML and filters dangerous URL schemes by default
- CodeMirror 6 editor with Obsidian/Typora-style live preview: block
markup revealed per line, inline markup revealed per element
- Fenced code highlighting via Shiki (github-dark, JS regex engine) in a
Web Worker, languages loaded on demand
- Lezer syntax tree to HTML renderer for share pages, checked against
the CommonMark 0.31.2 spec (640/652; 12 known parser deviations)
- Use markdownLanguage directly to avoid bundling lang-html/css/js
