CountDown v0.6
What use is it?
It's for counting down time.
Why?
I wanted to turn the computer off after I'd gone out.
How does it work?
1) Select the Time -hours, minutes and seconds.
2) Select an Action -application/document/sound/message or multimedia.
3) Click Go to count down the time.
Also
CountDown minimizes to a Tray-icon, but can leave a 'countdown' tooltip on screen.
