I think the header is too small

11-28 is a joke
11-14 is a sad fact

I for one, am satisfied witht he current list of events that is just filtered with the tabs (day, week, month - though I'd add "year"). It's a nice stable GUI that's not jumping between different view layouts.

What's the status here, does the month view exist now? Does adding year view makes sense?
