I have found that when looking through my inventory and bank, I often want to take or deposit all of my cooking materials or all of my alchemy materials, etc. With a full bag or bank, it is easy to miss one or two.

What would be really cool is a way to filter, such as a sub tab, or check boxes, or a drop down to show only the materials for the craft(s) I choose.

The same could be useful for weapons and armor too, but those are much easier to find, since there's generally fewer of them. So, much lower priority.
