New Gmail Inbox (desktop) (We don't have a larger GOOGLE forum yet)

This does not seem to apply to phones (not sure about tablets).

I just checked gmail on the desktop and I really like the improvements, the biggest being the fact that gmail automatically categorizes emails into primary/social/promotional (you can also further customize update/forums as separate tabs, but I find that unnecessary).

Probably the nicest update to gmail I have seen in awhile.

EDIT:

Just checked my phone gmail again and I see a similar update in that gmail app as well. Not as nicely presented as the desktop version, but still there.
