Looking for a addon that already has this feature or is easly configured to do so.

Id like to have items sorted in an inteligent way so that i can easly see my Defensive type gear, my Melee dmg type gear, and my spellpower type gear. in bank and in bags, while at bank or not. so that on raids or otherwize i can easly see if i should roll on an item or buy an item for offspec. 3 sets of gear is alot of gear to keep track of. someone must have made an addon like this. ofcouse for other classes, presets such as crit+spelldmg gear, +hit +spelldmg gear, etc. hope to get some tips on this, cheers.
