It's kind of funny how this isn't an option but with the power of illegal third party tools you can easily completely override everyone's glam.

I'm not really anti-3pp or anything, but it's been almost depressing lately when it comes to actual in-game glams. I can't be the only one asking themselves why they bother making glams when literally everyone out there seems to be using mare. So yeah, you might as well just let people be able to hide all glams through an in-game toggle at this point.
