What is the enhancement in mind? How should it look and feel?

1. Configurable "account" removal
   Removing inactive accounts after configured amount of time.
   
2. Configurable Bank Fees
   Configuring either Daily, Withdrawal, Deposit and by % or flatrate
   
3. GUI or All-In-One Scrolling signs
   It would be nice to be able to use the same sign to both Deposit and Withdraw from an account. With an deposit/withdrawl typed into chat instead?
   
4. NPC Bankers with GUI
   GUI holds "items" for buttons on Deposit and Withdrawl, with text entry or configurable amount buttons.
