Nothing like practice :-)

I can't help you with the module thing, but I would like to comment
on the whole idea of asking the user to confirm an action. This isn't
the best solution - it becomes a part of dimissing and you'll end
up clicking on "yes" before you realize you didn't want to get rid
of it after all.
Wouldn't it be better to push the dismissed morphs into a fixed size
(lets say 3) STACK and have a global menu item to retrieve the last
one? A little like the trash can in the Macintosh (there is supposed
to be a trash can in Kansas too, but I never saw it yet...).
