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

second page on slot selection screen (thing on bottom right corner to switch) second page has options

ability to rent slots instead of buy and an initial cost for slots. stop renting from options page by clicking an icon and then selection slots to stop renting and having to conferm by clicking twice or somthing and having global "dump" chests (or an admin only account) that items get put in if they are in a slot that someone can't afford or gets unrented.

let people with a permission node switch the account they are looking at/editing

ex.
/gb player Ps2maniac9 #switches account to be opened Ps2maniac9's (gb.admin)
/gb player #switches back to your account
/gb dump #switches to the dump account
/gb dump sort #moves everything in the dump account as close to slot 1 as possible (ex. slot 1 is empty/partialy full; slot 2 is full; slot 3 is full; as many items as possible move from slot 3 to slot 1)

I'm not sure about the renting idea. The main reason because if the player fails to rent the slot then they lose their items as you have said. Maybe you can think of a work around. I know you have suggested the dumping idea. But i am not sure...

However i do like the idea of being able to "switch" accounts. I may implement this. This could also be used for faction accounts etc.
