AdiBags is a wonderful "all in one" bag AddOn that supports the player's inventory, bank, and reagent bank. And its best part is that the display filters can be extended.
Thus AdiBags_Hearthstones came about, because I was frustrated with seeing the various portal and hearthing items displayed under "Junk" or "Other".
You can download this plugin (AdiBags is required) at either Wowinterface or Curse, and there is a page listing the currently supported items. If you see anything that needs to be added or removed, please let me know.
There are only eight (8) phrases that need localization, and I'm limited to English. If anyone is interested in helping, please jump in, and thank you!
The Wowace localization page is here. I'll flag new versions as people contribute
