Gmail and Docs on the desktop, along with a bevy of other Google services, features a side panel with shortcuts to Google Tasks, Keep, and 3rd-party add-ons. Google Calendar is another one of these shortcuts and it allows you to view the schedule for a single day, add events, and delete events. Soon, it will allow you to also directly edit events.
The current functionality for the Google Calendar panel is pretty nice, but it's not the full experience. It's annoying to be able to do most actions from the side panel but have to go over to Calendar to edit an event. Now, users will finally be able to do everything right from within the side panel. Editing an event includes the date/time, guests, location, and everything else you'd get in the full Calendar app. There's also the “Find a Time” tool to see others’ calendar availability when scheduling events.
Google will be gradually rolling this feature out over the next couple of weeks for Google Docs and Gmail. It will be available for all G Suite customers, but we'd be surprised if it doesn't come to consumers as well. A feature like this makes all of Google's services work better together and that is ultimately the goal. The less you have to leave a Google app (even for another Google app), the better. Keep an eye out for this in the future.
