The current sorting options are very good for a new character or a complete redo of an existing character. But when I just want to try out my latest unlocked dyes and see if I like them and want to incorporate them into my style, it is a hassle. You have to go to Achievement tab, mouse over latest achievements on General tab, find full achievement under more specific listing, expand it, memorize dye name associated, go to dye station, try to hunt down that color (is it Uncommon? Rare? Is that a shade of red or a shade of brown?), etc.
Sorting by date unlocked would make it much easier to locate the new dyes and try them them out.
Thank you.
