The holidays are fast approaching, and chances are you're already busy planning your schedule for the next couple of months. Knowing how important it is to stick to a schedule for seasons like this, Google has introduced a handful of changes to its calendar interface for the web. Now, you don't have to refresh it to see new items and changes (such as invitations or rescheduled events) anymore, since Google Cal shows them immediately. The Other calendars list on the left-hand menu now moves active calendar profiles to the top of the pile and buries inactive ones at the bottom, as well. Finally, your back button now works within the interface (it previously didn't), and clicking it brings you to the previous page you're viewing. While these are obviously pretty minor, they make using Google Calendar on the web faster and a lot less painful than before.
