The Themes Component allows you to change overlay designs with a single button.
Components are imported directly from within iRacing Live Timing. In iRacing Live Timing press F4 to open the Remote Control Tab and then F2 to enter Edit Mode. Click the Import Library button and select from the list the component you want to import. The component will then be imported to your Remote Control Tab in the first available empty space (often below existing components).
