Instead of naming all masks "mask", regardless of the type, it would be very helpful if they're named by mask type.
E.g. "brush 1", "brush 2", "linear mask 1", "radial mask 1" and so on. This way it's way easier to pick the right masks when copying the settings from one photo. Most of the time I don't want to copy the brushes, but only the linear and radial masks.
