Good advice for zero inbox, unfortunately most people aren't this organized and don't think this way and it seems like Google wants Gmail to benefit the most people.
Absolutely. I'm not saying they shouldn't do it, or that it's bad or anything like that. New email interfaces is just one of these things that has never been really useful to me. I tried Mailbox for a bit but it's solving a problem I don't have. This new feature seem as well.
