An idea I had, after I've seen this amazing BfA Alliance Warrior PvP set by chance, as otherwise I would've missed it as I barely look in the set list anymore:
- Grouping the sets by expansions would make the long list of sets much more legible
- It would enable you to quickly spot new sets
- Maybe similar to the updated crafting window, in which all recipes are sorted by expansions using a simple toggle for each expansion
- Either PvE and PvE sets separated by another toggle, or some sort of flag/icon to show if the set is from PvE or PvP
I did find several transmog addons that offer something similar, but they're separated addons.
If an addon like that is created it could be combined with other addons that track the amount of items you've already collected for a particular set.
