I would like to be able to have different balances displayed based upon different groups of bitcoin addresses.
It would also be nice to be able to see activity for bitcoin addresses for which I do not hold the private key (or if it is stored only offline) - this would enable me for example, to see transactions to addresses hosted by ewallets.
This feature would especially be useful if combined with another feature [raise audible notification when n (e.g. 6) confirmations received on a transaction].
