Allow various colors for events in same calendar
Sometimes it could be nice to allow to use for some events different color than default color for calendar. For example I have "Work" calendar where I have different types of events, like video meetings, irc meetings, other stuff and would be nice to be able to easy distinguish them by colors, even if they are in same calendar. It could be something what e.g. Google calendar is doing that there is (part) of frame on that incidence in the original calendar color and the whole rectangle is filled in with custom color. Wdyt about something like that?
