Here's a suggestion for Accounting:
I would be interested in seeing a tab similar to Resale, but instead pulls data from Crafting to show only items that I've crafted and sold with a Crafting Cost amount and a Sold For amount. I assume that storing the crafting price at the time it was crafted would probably require too many additions and changes, so you could just use the crafting cost at that time. The crafting cost would allow you to sort and see which item has offered the highest profit percentage, and you could also sort to see which crafted items you have sold the most of or made the most gold from.
Bonus points if you make it filterable by profession so that I could see only my gems, scrolls, glyphs, or anything else.
