[kronolith] Grouping calendar views

[chodek at chodek.com]

Hello,

Recently we run into the problem that we have too many calendars. The
problem is that when you try to see overview of the month it's very
difficult to find some events. We always can enable/disable view of
particular calendar. However it's difficult to use it when you have around
14 calendars. Is there any way to group calendar "views"?  Anybody else
experience similar problem? How did you solve it?

Thx!
