That's an excellent idea, thanks. It will help the eye flow better over the list of countdowns, to more easily see where one stops and the next starts, and is one of those little things that makes nice polished apps.

Will we be able to have multiple countdown applets on the desktop, each containing a different list of countdown events? I'm thinking of a situation where you might have one of the desktops dedicated to work events and one to personal, and want different things counting down on each screen.

Of course if you implemented this, the next thing I would be asking for would be to be able to merge and split the different windows, and to move events between them!
