Hi, xman! Yes I figured it out... same as I noticed that I can rotate canvas with key comb <ctrl>+<arrow left/right> and that <ctrl> acts as a color picker I am not used this a lot because to me it too slow process to rotate canvas.. I prefer strict 22.5 degrees angle, way faster for me. There is also mentioned "rotozooming" in MyPaint python code? But I think it is not usable.. (too slow). I am interested to find out how to remove "Volume notification" because it is so handy to customise those 2 (F7 & F8) keys to shortcuts.. especially when I working Portrait mode. But I do not like this "yellow bar notification". Does anybody know how to disable it... when I am using MyPaint. Yes, back to work.. now.
