Any interesting use cases for the idle handler?

Ive been in here bitching about this language every day, so I figured I’d change it up and instead just talk about an interesting aspect of it.

The Idle handler… does anyone use it for anything interesting?
The last time I used it was back in the 90s when I was first getting in to scripting. I had this one script running 24-7 on my old Performa . . . but sadly I cannot remember what it actually did. Like, at all. I had this script always running doing something for me back then but its function has fully left my brain. And I don’t have any of my old personal data from 97 to 03 so it will forever be a mystery.

But this post isn’t about my old scripts. I’m sure there are plenty of interesting scripts that make good use of the idle handler… if you have one, tell us about it!
