Engadget - In a move that'll likely have event planners and meeting organizers around the world leaping for joy, Gmail has just announced that you can directly add .ics calendar attachments to your Google Calendar without having to download and import them manually. Google's email service will automatically detect the event in question and display an "Add to Google Calendar" button as seen above. Just click that, and it'll be added instantly -- no muss, no fuss.
But you can still go back to the old layout if you prefer.
Overall, this looks like a decent UI update for people that use multiple Google services.
Spam runs rampant on Gmail, but you have options.
