Themes and language

Open Settings → Appearance and themes, or Theme in the Windows sidebar. Preview cards show the app surfaces, accent, text and connection button. Choose a built-in theme or create one in the editor.

The editor supports custom colors, a theme name and automatic black/white or custom logo color. Low text contrast blocks normal saving; a separate explicit confirmation allows keeping a low-contrast theme. Check labels and errors on your actual screen.

Themes can be imported/exported as JSON using the available actions. Provider subscriptions may offer multiple themes. Select a preview, then press Apply; selection alone is not confirmation. Keep current preserves your current theme. Provider options remain available in appearance settings.

Under Settings → App language, choose Russian, English or System. System mode follows the OS language when supported and uses a fallback otherwise.
