writer-fonts — piclaw-addons

Open Settings → Add-Ons and pick writer-fonts

Switch the document editor font from a dropdown embedded in the editor footer. Built for writing: pick a comfortable reading/writing face and the CodeMirror editor updates live.

Fonts

Option	Source	Bundled
System	the shipped UI stack (`-apple-system, …, sans-serif`)	no
Literata	SIL OFL — Google Fonts	✅ variable woff2
Georgia	OS serif	no
Inter	SIL OFL — rsms / Google Fonts	✅ variable woff2
Noto Sans	SIL OFL — Google	✅ variable woff2
Noto Sans Traditional Chinese	SIL OFL — Google (CJK TC)	✅ variable woff2
New Tegomin	SIL OFL — Google (Japanese serif)	✅ woff2
IBM Plex Sans	SIL OFL — IBM	✅ variable woff2

Bundled faces are served from the add-on's own asset route and registered with @font-face; "System" and "Georgia" use OS fonts and download nothing.

How it works

A Font <select> is injected into the document editor status bar.
The chosen font is applied only in Markdown live-preview mode (the reading surface, tables and frontmatter). In plain/raw view the editor keeps its default monospace font and the dropdown is disabled.
Live-preview state is read from the editor's own "Live Preview" toggle button (.active), mirrored onto a wf-live class on .editor-pane that scopes the override.
The choice persists in localStorage under piclaw_writer_font.
Scope is limited to the in-app document editor; other CodeMirror instances (e.g. the plan sidebar) are left untouched.
Code blocks and inline code intentionally stay monospace, even in preview.
Both frontends are supported: the classic UI places the picker in the editor status bar (next to Whitespace / Vim / Save); the visual UI appends a footer row to the editor frame.

Notes / limitations

Affects the in-app editor. A popped-out editor window is a separate document and is not currently themed by this add-on.
The CJK/JP faces are large (Noto Sans TC ≈ 5 MB, New Tegomin ≈ 3.7 MB woff2); they are only fetched when selected.
