Both of those are really good to hear. I've often dreamt of two things:

Making a completely bespoke little bluetooth macro keyboard with maybe 5-10 keys on it.

The other is probably further off, but I want movable keys. Not custom PCBs laid out how I want, but some way to move keys around, so I can say "today the escape key should be 2 mm down" and move the key.

The first might happen, but sadly I suspect the second is very expensive, and has a customer base of maybe one person.
