I definately agree with many of the suggestions already made here. There are a lot of great ideas.
One thing that I have not seen listed that I would very much like to see added in the near future:
A Kinship Bank profiler. Some feature that would allow one of my characters Inventory/Vault be listed in a Web capable format. This would allow for easy updating of the Kinship Bank Characters inventory for everyone in the Kinship to see. As it is now, the only way to allow other members to see what is in your Bank Characters inventory is to manually go through each item. That can be extremely tedious when working with mass transactions daily.
Thank you to LOTROInterface for getting the ideas out there. I have full faith that with your experience you can convince the devs to rework some things
