I'd like to suggest adding a "Search" function to our Storage (if it hasn't been suggested already). 

If not a Search function, maybe add a few more categories?  "Potions/Elixirs" and "Battle" are the two that come to mind first for me.

XD I've been meaning to suggest this myself.

I'm sure we'll have this in the upcoming site update.

A custom category feature in storage would also be amazing. (maybe as a purchased CS perk)
