If you haven't heard, Google+ is getting an events feature. "Party at Ron's house, 9pm on Friday, who's coming?" - that sort of thing. News of G+ Events leaked, surprisingly, through Google Calendar. Someone discovered G+ Events code in GCal - Apparently there will be some integration. Sounds plausible.
The Android app, of course, is going to need to support the fancy new events feature too. The other day in our AP chat, Eric pointed out a hidden section in the G+ App's navigation list. The list appears to end after "Local" but there's actually a blank button underneath Local, and tapping on the blank spot it will trigger a button highlight.
