I'm interested in a short review.
This in particular: is there *any* way tho make the "thumb modifier keys" send out key codes?
I bought the old Minila Air only for those extra thumb keys, so I can use them for my (sophisticated or crazy) keyboard config.
Sadly, they can only be configured to send "Space key", which is useless to me. I physically rewired the thumb keys to the Alt keys so that my mapping software can see them.
Otherwise, with new keycaps, the old Manila Air is great. Issues with multiple keypresses when the batteries are low, but all else is exactly what I want (including the hardware cursor keys). I'd buy a 2nd one, but I dread the rewiring...
