Designer Pixel Persona - Flood Fill needs 'Close Gap' feature similar to ClipStudio

[uuxxaa]

Clip Studio supports a feature called Close Gap for Flood Fill and I think just for that alone I can see people switching over to that app for certain workflows. It looks to be something that could be easily added to Flood Fill algorithm by widening the sample window on the reference layer. In my experiments with the AD I see that AD selects one pixel width/height for sampling.  When close gap added, AD would check a NxN square specified by the close gap. Unless of course 'Clip Studio' has a patent on it or something it should be rather easy.

Example: Drew it in AD and copied to CS and used pixel flood fill on both of them in the smallest circle

Before filling notice the gap in the small area and I am filling that

 

Affinity Designer  and in Clip Studio 

Wow I just noticed that InkSpace's vector flood fill does have Close Gap feature. Which is awesome.
