The Suite speaks Chinese — 整套界面开口说中文.
When Obsidian's language is set to Chinese (Settings → General → Language → 简体中文; zh, zh-CN and zh-TW all count), the entire Suite renders in Simplified Chinese: the settings tab — bundled-plugin toggles, every module section, the whole Typefaces console including all 24 rows, the pickers, and the 西文/中文 tab bar — plus both figure modals, all eleven commands, and every notice. About 150 strings, carried by per-module translation tables keyed by the exact English literals: under any other locale the English surface is byte-identical to 1.1.0, by construction. The four module display names (Tufte Sidenotes, Figures, Inline, Backlinks) stay English as product names, and nothing the plugins write into your notes — the Fig. label, callout syntax — ever translates.
One tab design. The figure modal's Basic / Multiple images / Image quilt tabs now wear the Suite settings' own tab grammar: native buttons, the active one carrying a 2px accent underline and semibold weight — the same bar you see under Typefaces.
Under the hood. New harness group t11-i18n (11 groups total): zh rendering across settings, modals, commands and notices; English byte-identity under three no-language variants; locale-prefix edge cases; and standalone-vs-Suite parity in both languages. Modules: figures 1.8.0, sidenotes 1.8.0, inline 1.3.0; backlinks stays 1.0.1.
Pairs with theme Tufte 1.18.0, released the same day — the Properties panel polish (warm-grey hover, no hairlines, one type register) and 中文 Style Settings live theme-side. Either works alone; together the whole surface follows Obsidian's language.
