Color scheme
Settings → Appearance → Color scheme picks between a light interface, a dark interface, or following your system setting.
Dock and app switcher
Mac only. Settings → Appearance → Show in Dock and app switcher keeps talat in the Dock and the Cmd+Tab list. Turn it off and talat disappears from both, leaving only the menu bar icon to open the main window. Useful when you want talat to sit quietly in the background and not crowd your Dock.
UI scale
Settings → Appearance → UI scale adjusts the overall size of the interface in 5% steps from 75% to 150%. Useful on dense external displays or for larger text.
