It would be nice if GIMP brush metadata could hold the
author/copyright/source url/other? information for each brush.
It would be really nice if certain tags for brushes could be generated
1. Type of brush - gih, vbr, or gbr (also abr? these are handled
2. Approximate size of brush - I use these groupings for "size" tags,
using the long dimension for brushes that aren't square:
~32px (and anything smaller)
~512px (and anything bigger)
So for example 100px brushes go in the 128px category and 80px
brushes go in the 64px category.
3. Author of brush
