Drawing gestures HUD

Hi, I've recently started using drawings (I didn't know you could set the drawing area size, and didn't test it further until now) and just realized that there's no HUD support for them uppon triggering. So perhaps a similar options that's available in other tabs to display a hud on drawing recognition would be nice.

Side question: is setting the drawing area to 0x0 may cause some bad thing to happen (performance, idk)? I mean, it works alright but I'm not sure if its a quirky thing to do or pretty normal.
