Sort Transfer Bank List

Currently when you make a transfer, a pop-up window appears asking which account the transfer should come from. It is currently alphabetical order.

Some better options might be:
 - maintain a count of transfers for each bank (or calculate on startup?), and sort by this "transfer popularity".
 - sort by most recent transfer

Another possible idea is to, when the user clicks the transfer checkbox, show a list right in the main page, auto selecting the top option, whatever it is according to which sorting method is used. This would make it easier to do, and more obvious what is happening.
