Sometimes when there are many obstacles on one place covering each other and I try to select one obstacle, I turn  obstacle displaying  off and  try to select it according to the collrect. To make this easier, it would be nice if the collrect changed its color, too, its obstacle is selected.

This is a good idea. I think it's easy to apply the disco mode to collision rectangles as well.

Yes, that's a trivial task.
