I appreciate Google constantly trying to help people. Honest I do! But to me this one is a pure fail. I had all the complaints others had, plus a few. Besides, really... how difficult can it be? Open an email. Read it. Maybe reply/forward. If not, choose Delete, Spam or Archive. (once in a while an email might become a task or a calendar entry, but mostly it's those 4 choices.) Repeat till inbox = empty. Repeat process daily or as needed, until inbox = empty, every time.
Suddenly need a specific email you archived 2 minutes (or 2 years) ago? This IS Google... search!
Can it BE any simpler/easier than that? I honestly do not see any need for "organization", tools, or features...Priority Inbox.. Tabbed Inbox.. Why? Even stars and labels... while convenient, they aren't truly necessary. Adding features to Gmail is like putting chocolate frosting on a flawless diamond ring. Might seem sweet at first, but it's likely not an improvement.
