Oh, you mean the laptop frame and trackpad? Anyway, I've made a diagram.

1. This is what you mean? Never happened to me.
2. Or is this it? Hard to believe, never happened.
3. This the bane of my hair, multiple times have I been stuck here.
4. This probably as well, not so sure.
5. My hand usually does not linger there, so no complaints.

Yes! I haven't thought of a solution yet, not sure also if it would be better if the gap was smaller or bigger.

For Framework I would suggest to just create a trackpad with the full width plate, possibly with a few different alignments. It would be a loss for modularity, I do understand that.

Easiest solution would be to just shave the hair, I guess? :D

As it happens, I just discovered this nice chap: https://youtube.com/@CinemaWins "Because liking things is more fun than not liking things."
