I'm working on v5 
Some progress there... It needs accounts, as opposed to UTXOs.
But there's a difficult question: UTXOs and accounts, or only accounts?
After reading about the issue of address reuse I think it wouldn't be that bad if accounts were used more (with different addresses). If you mean the same type of accounts here. But then it also has to have some kind of usability, so having that - what ever - running in the background would probably preferrable.
Btw great seeing you active and alife!
