Oh, I also have a feature request. I use a plugin on krita (Shortcut Composer) that makes it so that when hold down a keyboard key the horizontal and vertical movement of the stylus changes certain properties. There is a small deadzone, and then it locks to whichever axis it detects movement on. One "mouse tracker" maps canvas zoom and rotation to vertical and horizontal rotation, and there are others for brush size / opacity, scrolling through layers, and scrolling through undo history. I map the keyboard keys to my tablet buttons, and find these very convenient to use, so I would be happy if such functionality could be implemented in OurPaint. If you need more information I could record a video demonstrating this behavior.
