Sorry, I haven't read through the 151 pages of this thread to see if these suggestions have already been made, but I'll add it here.
Two features that would be nice to add to the wallet:
(1) Have a way to filter out dust/spam transactions when viewing your transaction history.
(2) Have a way to view your 'spendable' balance. I have many watch only addresses in my wallet, but just a couple that the blockchain wallet has the private key for.
Thanks,
John
