Google is getting better and better at integrating its stable of services, making the connections between apps like Gmail and Google Calendar tighter and smarter. Today, the company announced a pretty handy new feature for Gmail on Android that makes it easier to respond to calendar invites: those invitations now include a one-tap option to show your agenda so you can decide if you can make the meeting without having to click over to your calendar. It's not ground-breaking, but it's helpful -- if Google already has visibility into your calendar, it might as well show you that info in a helpful way. The new feature will work both with Google Calendar as well as Microsoft Exchange.
