This layout is based on @stephengrier TADE68 layout. Modifications in total are:
- Replaced capslock with a second function key (@stephengrier)
- Swapped the left ALT and Win keys to be more like the Mac layout (@stephengrier)
- Fn+x toggles backlight breathing mode (@stephengrier)
- Shifted volume controls one button to the right
- Maybe ALT+Umlauts Mods will work ;)
