I know the testing isn't focused on this yet, but the last engineering report mentioned that the bank was going to get worked on at some point. When it does, please keep this in mind:
Most of the people playing games now are used to a flexible, window like interface. I am accustomed to being able select items (using Ctrl or Shift) and dragging them to the file (or repository) that I want it in. I hope to one day do that and all the data, particles, and consumables will auto-stack for me.
So far, I haven't come across the bank bugs I have in the past (i.e. stacks that wouldn't move or having a whole stacks count against players when they only grabbed a couple). If they got fixed, I wish it would be mentioned in the updates.
Now that I think about, I my signature still has some ideas for the bank. That was a long time ago though.
