I have, in my Google Calendar account, several calendars which have been shared by friends/family/co-workers. Is there a widget which I can place on my phone's home page which will show whether or not a given person (or calendar) is "in an appointment" or not? I'm using a Samsung Galaxy S, but it is running a 2.2 build (Team Whiskey).
I believe Android Agenda Widget is similar in functionality to the LauncherPro calendar widget. It's quite configurable and has a wide range of widget sizes. Also shows tasks from certain supported apps.
Launcher Pro has a nice calendar widget that I use for this purpose. It can switch back and forth between a month view of the calendar to an agenda view. I have my own calendar and two other Google calendars hooked in which show up as appointments on my agenda.
