Beyond colors

The Appearance section also controls:
  • UI text size — scale the whole interface up or down with a slider.
  • Animations — turn transitions on or off.
  • Window rounding & padding — rounded panel corners and breathing room around the layout.
  • Titlebar balance — show or hide your balance in the top bar (handy for streaming or screenshots).
  • Data grid options — crosshair cursor, cell highlighting, and other table behaviors.
Themes apply per device, and your custom themes stay with you. On desktop, imported themes are stored as files you can back up.
