- Attachments from the file dialog, a drop on the window (Rust holds the dropped paths; the page never names one) or a paste (the bytes as the raw body of the call), sent at once to /api/v2/attachments as multipart and shown above the composer. - Edit message (rewind), Regenerate reply on the last reply, Copy on both. - The chat's menu (header and a right click in the sidebar): rename, open in the web interface, archive, delete. - The chat's model and effort in its header; effort for a new chat. Model avatars coloured as the server's stable_hue colours them (MD5 of the id, checked against Python), mixed into the theme's surface so no colour is hard-coded. - Ctrl+K palette over commands and every chat's title; Ctrl+N, Ctrl+,. - The agent's new states in the page; 34 new sentences in all eight languages, the server's own words where it has them; a Czech row that was Slovak; two untranslated strings.
