Wait, I've been googling gcal for the last 2(?) years when my calendar tab needs populated when I could have just been clicking on the chessboard thing in gmail??! I was wondering where the hell gcal went! >> Google decided to hide other apps behind an unclear icon in the Gmail UI, they apparently got a stream of support requests, like “Where is my Google Calendar?” <<
