Hmm. Interesting.

If you don't mind me asking, could you describe what alternate keycaps were used? Like, taller keycaps in the front, shorter in the back? Like, I still think that the amount of keytravel would be a negative, but maybe the issue is that the long nails descend into the keyboard given the normal position of a hand typing, and basically changing the angle improves that.

If that's the case, I'm wondering whether maybe it'd be possible to change the angle of the keyboard as a whole. Like, either use an external keyboard propped up differently, tilting away from the user, or a laptop with the front part of the base shimmed up to tilt away from the user.
