What version(s) of WoW are you using?

Retail

What problem are you experiencing that led to you asking for this feature?

With the new warband bank, I put BOE and warbound gear in it for my characters. However it's a pain to check which gear can be used by the character I'm on.

What solution would you like?

The old UI would color the icon red if I couldn't use that piece of gear yet. Something like this could be really handy, or some other indicator (a red arrow in the corner.)

Any alternatives you can think of?

A red arrow in the corner, or a red border, something like that which isn't obtrusive but still an easy-to-see indicator for items that are unusable yet.

Anything else?

Thank you :)

You can search usable to see any items that can be used by the current character
