I can’t tell you how many times I draw an expression on CC1 or CC11 just to realise I have to turn off snap. It’s driving me completely insane. It would save me hundred thousands moments like “ahhhhhhggggghhhh!!!” … take a deep breath, deactivate snap and then draw a nice smooth curve.
Seriously, 99.9% of the time, we don’t use the draw tool while snapping to grid. Just make the pencil bypass the damn grid by default.
