I have not tried the Humboldt application. Perhaps I should look into that. I think that it uses the calendar though, so I don't think that it is an en masse activity date changer like yours.
I wish that mod/quiz/index.php had an "Turning Editing On" button and one were able to edit start and stop dates from there. But a block would be okay too.
Alas, however, it seems that there is not a great deal of interest.
