Additional transaction info to avoid generating unique addresses for each customer.

Ability for the client to easily import addresses. Maybe even include the vanity gen into the main client :)

Current built-in alert system can become useless if the client itself is compromised. I suggest to setup an alternative system of alerts. Since alerts are signed, there is no need to have trusted "alert nodes". It can be just some cloud...

Split the client into unprotected block-chain server and wallet managing front-end that handles URIs.
