dsh-ui-font

DSH's default font pairing rarely balances the comfort of Chinese typesetting with the legibility of code blocks, and adjusting it usually means rummaging through CSS. dsh-ui-font adds a dedicated Fonts panel under Settings: pick a body font from presets like Microsoft YaHei, PingFang, Noto Sans, Xia Wu WenKai, or HarmonyOS Sans, or type any custom font stack; code blocks get monospace presets from Cascadia Code to Maple Mono NF with full custom support. Independent controls for 80 to 130 percent display scale, 1.3 to 2.0 chat-area line-height, sub-pixel antialiasing, and code ligatures round out the panel, all applied via CSS custom properties for instant feedback without a restart.

The font browser is the highlight. A child window lists every installed font, each previewed in its own glyphs, and a single click applies it. Fonts without CJK coverage carry an EN badge and trigger a selection warning, so Chinese text never silently falls back to a system default. If the browser's Local Font Access API is blocked, the list degrades to a curated common-font probe, and you can still type any name by hand. All preferences persist in localStorage across reloads, and a single click restores defaults.

This is a pure client-side plugin with zero backend impact: clean install, clean uninstall. It is built for DSH users who care how agent responses, tables, and code snippets actually look on screen, for Chinese-primary readers who want reliable CJK rendering, for developers switching between Chinese and English workloads, and for anyone who simply wants a more pleasant monospace face in the code pane. No CSS files to edit, no server restarts. Open the panel, preview in real time, and find a satisfying combination in seconds.
