That seems like a really good plugin idea for V3 and would make it easier for deployers that don’t want to upload 3.9MB worth of icons individually. I think a plugin dev could take this a step further and have it automatically set up categories with the official category names (if they are somewhere) and corresponding icons. It might be easier for deployers to then go in and simply remove the ones that aren’t relevant to their deployment.

I think plugin development for V3 might not be quite ready but I would say this one gets my +1.
