This is an all bags open bank mod, This version allows for up to 14 slot bags in the bank and 20 slot bags in the shared bank. I'm pretty sure it was at one time based on Danoris's Fully open bank - all slots visible, no bags open .
The crashing/losing items issues that at one point came with bags open bank/inventory windows are all solved! if the bag has fewer slots than 14 the bank window will now show however many slots there actually are in the bag instead of displaying nonexistent slots that eat items.
