With the 'old' calendar plugin, past dates could be searched easily using 'week' and 'year' drop down.

In the new 'Team calendars' this is possible from My Calendars. However, this drop down functionality would be really useful on certain public pages where the team calendar macro is used. I don't see why this should be limited to just 'My Calendars'.

This is especially relevant for those who have taken so much time to import their old calendars and still refer to dates from years ago...
