Interface & preferences

Instant language switching, notification center rules, and the update check entry.

Interface language

"Settings → App → Language" switches between 16 languages (简体/繁體中文, English, Deutsch, Français, Español, 日本語, and more). The switch takes effect immediately — no restart needed:

• "Follow system" matches the UI language to your operating system preference;
• The UI itself ships fully translated for all 16 languages (including Traditional Chinese);
• The user manual and the website docs currently come in Chinese and English: a Traditional Chinese UI reads the Simplified page with a language hint bar, and other UI languages read the English page with the same hint bar;
• The preference is saved and applies on the next launch.

Notification center

The bell icon in the lower-right corner opens the notification center, keeping the last 50 notifications (newest first; in-memory only, cleared on app close, never uploaded):

• Error notifications (send failures, install failures) are archived automatically for later review;
• Empty-reply reminder: when the model returns no content, the notification center archives a reminder in addition to the in-message "Retry" button;
• Routine hints only appear when needed.

Check for updates

"Settings → App → Update check" checks and installs new versions; auto-check is on by default (can be disabled). Fully exit the app (including the system tray icon) before installing an update.
