Currently the blacksmith sorts all gear by Pet Name; I think it would be nice if there were additional sorting options, mainly Sort By Equip Rarity and/or Sort By Equip Upgrade Level.

As it is I have to scroll through a bunch of stoneweave and vinethorn equipment that I have on Mission pets or am storing on random pets to spare inventory space, trying to find the stuff I want to upgrade for actual battle pets.
Basically, it'd just be a Nice Convenience if it was possible to add a feature like this, though I don't know how feasible it is, not knowing how the system is set up internally.

if possible, i would also greatly appreciate a system like this.
