When creating loot filters by affixes the affixes aren’t in alphabetical order. For example for mages, "Level of Volcanic Orb, "Level of Black Hole, "Level of Static Orb, "Level of Lightning Blast, “Level of Focus” are sorted in that order. Alphabetical sorting in (sub)categories would make it easier to find affixes I want to include. Search works too, obviously, but sometimes you know what you want in a group and don’t need to search individually.
