Would anyone else find it useful to be able to select groups of glyphs based on their color tag? It can be tedious to go through and select them one-by-one.
I think it would be quite useful at times so I want to ask that it be added to the Feature Wish List.
The other possibility is a script that would allow the user to select one such glyph and then run the script which would do a Select Similar based only on the color tag.
