Unfortunatly, i can not get the multitouch features to work as described. I tried pen only mode, and pen and finger mode: in pen only mode nothing happens when i put a finger on the canvas. In pen and finger mode, the shape or line freezes when putting a finger on the canvas, but without snapping to an angle or ratio.
In the transform tool, gestures only move the canvas, but not the selection. Basically nothing happens, in neither drawing mode.
The new expand function does not seem to work. Whenever i set a pixel value other than zero, the fill tool does not do anything.
I like the color bar in drawing mode, the switch is quite ingenious and works well. What i find confusing in the drawing mode is the position of the brush and color editor. It would make more sense to me, when the brush editor window would pop up when clicking on the tool icon at the top. The color icon could perhaps be at the top of of the bar at the left (size and opacity) above the switcher and permanently visible. This would clean up the UI. The switch between pen only or pen/finger mode could be in preferences, as i don‘t believe you would switch between these modes frequently. What i miss is the „...more“ menu from the normal UI, which i use mostly for switching drawing mode or brush blend mode.
I have some more UI ideas, but i will post these in another thread.
