I downloaded Jiggler a few weeks ago, and just used it for the first time this evening. I used it to keep my laptop from dimming the screen while I was watching a movie (I have to re-register for Quicktime Pro after my laptop had a little bit of a misunderstanding with me, and I haven't done that yet, so I was having to watch in Fit to Screen sizing), and it worked like a dream.

However, if I were to improve on this app, I would make the Jiggler active icon a bit smaller and transparent, and include a way to move it out of the center of the screen. Since it's easily disabled, though, it isn't a big deal.

Also, the app is free, so it's not like a small annoyance is worth crying over. =p Thanks for the app!
