P: Modifying previously applied Healing region (stroke)

If you are fixing sensor spots, the default round region for healing works fine.

However, if you are trying to remove something bigger you start filling out a larger region.

There is the chance, especically if using a mouse, that you make a mistake defining the region.

There is currently no editing mode that allows slight modification of the region and the correction updated.

A good example is Exit signs in darkened theatres. You think you have defined the region for removal but what you haven't seen is the subtle glow a little outside the region. So you end up having to define the region again - this time a little bigger. All I wanted to do is add to my healing selection region (or remove some).  this might suggest and expansion feature that maintains the overall shape by scales it up a little, post mouse up.

So Healing could benefit from the add/subtract feature found in the masking tools to make adjustments to the region selection.
