It’s been so long since the first cosmetics and skins came out. They’re nice, but the only things that are missing are inventory sorting and organization. It’s pretty tedious to look through your inventory before (re)equipping or whatever you want to do with the items.
Basically:
Add a sorting option to arrange your items according to the one you selected. E.g. Sort by date, rarity, item type
You can change the sorting direction with ‘Ascending’ and ‘Descending’
Allow item dragging to place in your desired inventory page
Make it remember whether or not skins, cosmetics, and/or mythicals were enabled/disabled from last time on the server. Maybe have that information forgotten after not playing on the server for 5 days or so, as to keep stuff from clogging up too much.
