Bug switching from eraser tool to the new curve tool

Hi, today I updated blender 2.8 and tested the new tool in grease pencil, the curve tool. I saw that it doesn’t work when you select the curve tool when you come from eraser. Only works correctly when you choose the brush tool and then the curve tool. I would like to try to make those changes to the code but even if I could arrive to do it, I don’t know how to make commits. Anyone can paste some tutorial on how to do those tasks of committing something ? Maybe if you make a video on the developers you-tube channel more people could help with little things like that. Anyways, that’s an awesome tool for giving to an animation that finish look (great to make straight curvy lines) :slight_smile:
