I'm on Linux and totally going to give this a try. I switched from multiple monitors years ago to just a laptop and am in permanent portable mode.

I use the pointer stick exclusively so don't have to reposition my hands on the keyboard like with a track pad, but the pointer stick does keep my hardware choice limited, currently a X1 Yoga. If Mouseless would be faster, then I could get a Framework (no pointer stick available).

I'd gladly pay the $50 for lifetime.
