Completely agree! The author made a buggy android port of nintype (called keyboard 69) that I used for years. The UX was incredible, and every swipe system I've tried since feels downright clumsy by comparison. Two finger swipe is peak ergonomics, but unfortunately I think it's an innovation that's simply too niche.

I used nintype and keyboard69 for years, heliboard on f-droid supports two thumb swiping and works very well ! Not as good as nintype but extremely useful
