Dasher

It's an easy mouse click or keystroke away when you're in front of your Mac and need to take a peek.

But what about when you turn your attention to something else or walk away for a few? Wouldn't it be neat if Dashboard popped up by itself after a certain amount of system idle time? It will be pretty neat indeed, right after you download and install Dasher, a preference pane that gets your Dash' on automatically.
