Late game its easy to get a ton of skills and often I found myself when reskilling for a certain encounter (which happens often), that I have to scroll through long lists.
Also when looking for a certain recipe in player shops, I spend literally tens of minutes to scroll through every recipe to find the certain one I am looking for.
Maybe different options for sorting: Sort by name (useful for player shops), Sort by frequency of use (useful for reskilling. This later could use a built-in Presets option, where I can configure X presets: pvp, tanking, healing, undead fighting, whatever)
