Here is what the GUI shows me:

One little thing i'm seeing is that swap Fn keys when set on status "ON" deactivated the functions and functions normally. This means that when it is on, the system processes media functions without pressing the fn key. I don't know if this is intended or a bug.

For devices that support HID++ 2.0 (and above, but they are all really only HID++ 2.0) Solaar can discover the device's features (shown via solaar show) and show and manipulate some of them in the GUI.
The documentation in devices.md should be updated to reflect this.

The Swap Fx function when off should result in the function keys sending Fn codes when the FN key is not down and the "special" codes when the FN key is down; when on the reverse is true. The tooltip on the switch should so state.
