Are you thinking of something else than winforms?

I believe winforms and WPF has always been usable but not with the visual designer tooling in visual studio.

UWP has been trickier though to my knowledge.

Are they well supported in both AVR and ARM/chibios versions of QMK? Are there any differences in how they work on a thinkpad and with QMK?

On my old thinkpad the cursor would sometimes start drifting and you have to release the trackpoint for it to settle - is that something that is handled by the firmware or inside the trackpoint module?

Asking as someone who plans to build a custom keyboard (preferably with arm mcu) and have a trackpoint module waiting with the pinout figured out.
