Full Cal - Mozilla add-on that allows you to see a larger calendar view on Google Calendar.
Version: 1.2When you first load Google Calendar, either by navigating there on your own, or using the extension's shortcut key (default is Alt-Shift-C) it will place an unobtrusive button on the page (see preview).
Operating System: Mac OS X
You can use the button to hide/show just the left sidebar, or you can use the shortcut key to hide the sidebar and headers at the top of the page. With the headers hidden, you can still use the button placed on the page to pull out the sidebar again.
Full Cal also adds a button that you may choose to place in your toolbar (by right-clicking in the toolbar and choosing "Customize...") which does the same thing as the shortcut key.
