Sounds pretty reasonable, especially if you have a touch screen or otherwise drawing on a screen. I just played around with the hide option, and I can see how it can be annoying for quick hatching strokes. I would suggest we create one more option to totally hide the cursor while it is on the canvas. I think we still want to show the cursor for file menus and other non-canvas stuff, right?
I’m also wondering if we could add a delay to the current hide-while-drawing feature, so that quick strokes do not show the strobe-like reappearance of the cursor. When you’re drawing quick strokes you really are not using the cursor as a reference at all, it is more muscle-memory or something. I think waiting one second after the end of the stroke might be enough to help quite a bit.
