If you're only planning on changing the color to group them, why not just add a text string with the assigned color per group linking the name of the mod to that color coded group, that way you don't have to change the mods.
just a thought.
I meant in a lua file or something, obviously my opinion and trying to offer a suggestion when un-noticed.
categorize in lua with the mod title wrapped in color code tags would be easier than all this arguing and you wouldn't have to alter anything at all, thus no debate.
eg:
Quest Mods
|cff4169e1QuestGuru|r"
etc.
It would save all this debating over policies etc.
