 - The upper left button switches between light and dark mode (*dark mode is not yet implemented*)
 - The upper right button is used to switch between multiple remote controls. You can configure as many remote controls as you like, allowing you to control an unlimited number of devices via FernoPy. However, the maximum number of groups and participants per remote control still exist in FernoPy (7 groups with 7 devices each).
