Not sure about private trackers but on public ones, I did not see them anywhere. Also chances are not that high since it is old material that never got translated into Englosh or other languages, so quite niche.
Sorry, saw the reply just now. I use Wayland pretty much exclusively since I switched all my devices to Linix roughly three years ago and I face no issues. Afaik sway is fully compatible with i3 config, so I assume your gestures should just work the same. Hyprland is a different beast, it is still pre-release, so while the state is impressive, do not expect super advanced niche features like gestures (check their wiki to see if they are supported). I don’t use an OSK, whenever I fold, I pretty much use only xournal++ which I navigate with pen and touch. However, there is at least one that I tinkered with some months ago and it worked, I cannot remember the name though (probably got it from the arch wiki). Lid switch detection works well in sway, so I assume configuration for it to come up automatically should be trivial. Again, definitely try sway first, this should give you the best experience. Hope it helps!
