IMHO in guild rank permissions, together with actual Deposit and Withdraw, should be added Stack Items in guild bank.
So the guild leader could have the rights to allow other guildies to stack items in bank without waiting for him/her to be online.
It would help in better managing the bank space when many people deposit items and bank becomes full for long.
Especially depositing single pieces of crafting materials can fill the bank very fast.
