This project is based on this weakaura
Shows icons for each mat you have in your bag/bank.
Inside icon is BAG quantity, under icon is BANK quantity, the above icon is the total. It is profession based so only matching items will appear. It has a SHOW/HIDE toggle switch. It will not load in instances.
This version of the aura is only showing TBC materials, but you can add more items using the custom config tab on the auras. You need the item id which you can get by addons or searching for the item on wowhead.
The auras are showing only if you have skinning/herbalism/mining. If you want them to be visible any times, you have to change their first trigger.
All changable settings are found in the Custom Options TAB.
You don't have to keep all auras in the same group you can create seperate groups for each profession, etc.
