Alright, as you can see, the compatibility for 40% is just… not good… Even with these 2 blanks for the spacebar.
If there is enough interest I could make a 40 kit which would include 1u shift, Enter, Tab, Lower, Raise, etc.
But if I do so, people with staggered 40 will ask about special Shifts and Enters too I guess. I'll think about it.
Also, in order to Cover HHKB
(real) layout, what about adding 2x 1.5u Code in the base kit?
So it's: Alt - Code(Cmd) - Space - Code (Cmd) - Alt
