It seems like it could be really useful to have the curve points turn on when a curve is selected. I think it would also be useful if they turned off when the curve was deselected. Is there a reason to have them stay on?
If they do stay on, as I work I’ll just turn on more and more points in my file until I hit escape enough times to turn them off. I suppose I could get used to that, but it seems like it doesn’t really have much benefit; it just adds steps.
