As someone who has many characters with crafting mats, this was a godsend. It was impossible to keep track of which toon has which trade mats, and this makes it much more simple.
One question-- is it possible to change the format of the list? Right now, it looks like:
<Item>
17 in Warrior's Bags
1 in Warrior's Bank
3 in Death Knight's Bags
18 in Death Knight's Bank
Instead, could the text be reformatted to look like:
Warrior: 18 (Bags: 17, Bank: 1)
Death Knight: 21 (Bags: 3, Bank: 18)
And have the text color match the class color for easy reference (i.e. Warrior would be brown, Death Knight would be Red).
