True, but having 100+ guns in a bank may need even better options than what BL2 offered. Plus, there, you could only see a relative few at a time, whereas here the icons will be smaller. We'll have to wait and see, but my guess is if they don't offer stuff like tab naming and such, people will demand it pretty quickly.
We don't have that in Destiny and no is demanding it so I'm sure it really that big a of a deal. Sorting by item type works for me, but I do want to be able to see more than like 5 at time.
