I've this installation:

- All zimbra users have a task list shared with the Big Boss.
- Big Boss see all tasks lists shared by users.

Big Boss want:

Until there are tasks with status "not started" foolder need do be highlighted
(I don't think it possible)

A query string that extract all "not started" tasks searching on all shared tasks list. (I think possible but zembra help explain only search tags to search in email folders)
