It gets to the point where you have several bags, quivers, pointless Necropolis extra bags etc... that you may have stored in various parts of your bank space or even organized onto one mule. Trying to find a particular one in your sea of look-alike storage items can be a real PITA. Having to haul them into inventory everytime you need to peek inside, just to find out that "Nope, wrong one!" and on to the next clone bag or quiver or whatever. It would be nice to improve the functionality of the bank to allow us to open these items in their bank slots instead. Here are three ways, in decending order of preference, that I think would improve it:
1) When we double click on a storage item in our bank (shared or personal) it will open to reveal its contents just as if it were in our inventory. This would mean that these items would have to be dragged into inventory or other bank areas if they needed to be moved.
or
2) If doing it with the shared bank is not possible/practical, I'd settle for just our personal bank.
or
3) If none of this is possible/practical I'd settle for the ability to mark our possesions somehow so at least you can tell these things apart.
