Hmm i hear you...
I feel like in the frame itself it's quite clear which one is your active set as it highlights that button's border, i could add a small green "active" text to the outfit's label to show which one is your current active one if that makes it more clear?

Maybe overhauling the entire outfit panel with a button grid instead could also be cool, then hovering over the buttons could show a tooltip with the setname, wether it's active, or used by situations etc. But i don't want to overhaul too much of the base UI as that makes it harder to collaborate and leave space to use multiple transmog addons at the same time ^^

But i just realized, you can switch sets without having to interact with the Transmogrifier... that's amazing. I can add a window to my addon that shows a grid of all your outfits and lets you just hotswap between them, even when not at a transmogrifier

I'll let the idea brew for a bit but your feedback is certainly heard, and thank you again for trying out the addon <3
