Wooo, just seeing this thread for the first time.
1) Awesome
2) i vote that with a typical "ansi" layout, the outside edge of both shift keys should become a single "1x" modifier.
3) I wish i had something more to contribute.
I think... small, sturdy, and programmable, would be f'sweet (and bonus points for being able to use "standard" key cap sets for it).
I only recently found the phantom thread on DT, read the whole thing, and was bummed at the end when i realized i'd never get one.
This, though... kinda gives me some new hope. (and something to "wait for" lol)
Will certainly stay tuned. ^^
