Inventory bag compartments.

I know it is a memory issue to have compartments in our inventory bag for storing items, but is it hard to have separate compartments in our inventory based upon the items? Say like the crafting materials. Could there be separate compartments for Woodworking, Leather, Culinary, Goldsmith, etc. for the materials we gather? My inventory right now is just so filled with filler items I have gathered just to do crafting, it has been impossible holding the materials for all of my crafting classes. I know we have the Armoury Chest so our gear can be in it, but can we have a Materials Chest for gathering materials? Say like how the Armoury is set up with having main-hand tools, head gear, body gear, second-hand tools, etc. but with crafting items?

Then our main inventory could have excess finished products say like cooked food, potions/ethers, extra armor/weapons, and the like.

I'd like a GW2 Style Inventory System that allows you to carry all your crafting/gathering mats with you at all times without running into an Inventory Issue. And a Tackle Box separate from the main inventory.
