Inventorian BoE is a simple addon that does one thing:
adding a BoE label on the item icon in your bags for equipped items
and now, among the many items in the bag, you can easily identify items that can be sold at auction, or transferred to another character, or for any other purpose for which you need it :D
The addon comes as an addition to the addon Inventorian.
Install and go!
See the picture in the Images tab. That's all, have fun!
