I don’t think we currently have such a script but I believe it would be useful.
I frequently use filters to identify glyphs or to add/remove subsets of glyphs to my working charset. It would be a time saver to be able to mark such glyphs with a color in such cases where the glyphs are a portion of a much larger list.
A script that would select all the newly added glyphs, similiar to the existing “Select Same Color” script would be a big help. Something along the lines of “Select All Changed” would work since the glyphs are initially marked as “changed” after being added.
Can someone do this for us?
