Another project I didn't quite get finished for GIMP 3.2 was non-destructive filters on layer masks.

The limit itself was easily removed - the challenge was making a good interface for editing filters on both the layer and its mask.

My first version used tabs, but @aka_reju suggested I show both groups of filters on the same screen. The video shows a demo of how this works. Once I get it finished and update the merge request, we'll see what people think of it!
