I've disabled the new groups "social", "forums" and the other few, because I like all of my emails to go into one inbox, but I do not get notified when I get a new email, only when I get a new email that is marked as belonging in one of the new groups added in the update. I've searched google and there's only been one thread mentioning it, but their goal was slightly different to mine.
Specifically, I would like to get a notification when I get a new youtube subscriber or message, which goes into the "social" page, therefore it doesn't notify me.
However, I got a notification for my
picroma.com account activation link, which went straight into the main inbox.
