Looking for a Collections UI Highlighting addon

Aelthwyn

With all the different costumes, pets, mementos most of us have been amassing over the years (and especially since the randomness of the crown crates), it would be really helpful to have a way to sort of highlight, or black out various ones per character so that when you go to select something new it's easier to find the ones you actually might want to use for that character. I'm picturing something like inventory grid view's green box borders, making it easy to spot the things relevant to a specific character.
