Great job so far! A couple of remarks for logi options on macOS: 1. When a user customized system wide shortcuts (e.g. for desktop switching), and selecting the desktop switching functionality, it doesn't work (and the user doesn't get any feedback on why it doesn't work). Being able to just assign custom keybindings for each button would make things easier here. 2. For horizontal scrolling, it would be really nice to be able to invert the scrolling direction (just as macOS offers for regular scrolling).
