got it to work finally- it's not really better than the one i already had set up before, but anyway- it's something!
Sure it's bad that if you work with a tablet you have to move the pen far enough out of the recognision area to rotate with the navigator correctly.
And you can move just on one axis at once.
Btw, is it on purpose that the standard axes of the navigator are set in a way that you can't press the two buttons? That would be way more ergonomic.
Some years ago i made a workaround to reset all axes so x is y and so on.
Thumb on button one, middlefinger on button two.
I'll have to fix that in this version as well- otherwise it really unpractical to use the buttons effectively.
Maybe you could make a patch to fix / change that easily??
