All browsers: Want your Google Calendar to look a bit more like a desk calendar—all appointments, no filler? The Mini Google Calendar user script cuts out everything except your data view, relying on keyboard shortcuts for everything else.
I LOVE this script. It gets rid of all the annoying space-killers in GCal that prevent you from seeing your whole day at once. The keys to remember: “q” adds a new event (or just click the time you want), “1″ is day view, “2″ is week, and “3″ is month.
Google Calendar finally became usable for me. Get the script here.
