@fair I know that, as per your other thread on this topic, you just don't like gestures. But if you don't manage to make buttons, or even just until you do, you could consider trying the UT Tweak Tool, and playing with the settings under Edge Sensitivity.
Changing the edge barrier width can make a big difference.
I wouldn't personally want these options, but perhaps others would, and will speak up here.
I suspect that if others wanted it too, if you got it all working, and if it were totally stable, it's possible it could be introduced as a system option down the road. But it wouldn't happen quickly.
As an example, I understand that the wonderful manual screen rotation tool from Ambot Installer / Lomiri Plus got introduced as part of the OS in 24.04.
