Given how much space the non-calendar part takes, I'm also surprised as to how little content fits in it. In the old calendar, the left sidebar was [in my standard browser side] big enough to show 6 "My" calendars and 5 "Other" calendars, with blue borders cleanly delineating the sections, and colored backgrounds making it easy to visually link calendars' names to their events. Now, the left sidebar, in addition to wasting ton of space, separates sections only by slight vertical gaps, makes almost no use of color, and displays [same screen size] 2 of "My" calendars, and 2 "Other" calendars. The generally garish color changes, I could live with. Mushing the UI components together into a sea of whitespace, making them less distinctive, and wasting most of the screen, on the other hand...
