You’re right, it wouldn’t necessarily work as well with high profile MX switches, unless someone has bigger hands. Having only 2 keys on the inner index column helps to mitigate some of the extra reaching - but, that’s not for everyone. Ideally there would be no inner index column. One day…
Good to hear. Yes I will make this open source, hopefully within a couple weeks.
It’s actually concave, in that the pinky and index are higher off the table, like in the Dactyl. It looks convex in the photo because the columns are angled outwards. The other photos might show this better. EDIT: I picked a better photo for the post to make the shape clearer.
I get that, this design has been brewing for years with no visible progress until recently.
