Thanks for the reply. The 3d cursor doesnt bother me, in fact I find it really useful for grease pencil drawing. My question was aimed at eliminating the arrow of your mouse cursor while GP drawing or sculpting. I am using a pen display and having the white arrow between me and my subject matter is really annoying. Ideally if it disappeared once the pen was engaged would be best. Even minimizing the mouse cursor while drawing or sculpting would be amazing. Like I said it seems like a simple UI toggle, and one that other programs seem to have dealt with, I just cant seem to find it in blender.
All the same, thanks.
