I'm not sure if this has been suggested yet, or if there is one but I haven't found it yet (I'm fairly new so I haven't explored much), but I think a bank would be great to have. 

The reason is because I usually have this urge to spend however much I have on me, so if there isn't a bank I end up buying random things, or in the case of this site, researching genes when I should be saving up instead. It just makes it harder for me to save my money to build a new building. 

The bank doesn't have to have interest or anything, I would just like some place to store my money. 

Support. Banks are pretty standard in these games. I don't need interest either, but I'd like having somewhere to squirrel money away. I'd like a Vault system too for items I want to keep for certain things but don't want cluttering up my Warehouse.

Yeah I was going to suggest a deposit box as well, but I don't know if that would work because you only have a certain amont of space in your Warehouse, so having a Deposit Box or Vault to store more items might not be what they want. I don't know though. If someone thinks of a good idea for a Vault/Deposit Box then I'd definitly support as I want one too. 

Support~! I think it would very nice to have a place to store silver and items. I know that items in deposit box or vault would offsite the warehouse limit...so how about scheme to build one? Maybe give it a limit and you have to upgrade to increase the limit...

Ah okay, my apologies. I only looked to see if there was one labeled as 'bank' on the first page and didn't look any further :P 

It's nice to know that so many people want a bank though. :3
