Gmail and GreaseMonkey

So I finally got around to playing with GreaseMonkey... and I regret not doing it sooner, there's so much I could have done already!

If you're not familiar, GreaseMonkey is a Firefox plugin that lets you add your own/custom javascript code to websites. And it's dead simple - based on a handful of specially formatted comments and a file-naming convention, your javascript becomes custom code you can use to modify any site you want.

I used it to write a scripts for Gmail - when I switched over recently from mutt and pine (I know, to all you text-purists out there: I'm sorry, but I couldn't help it...) I lost the ability to use my nifty cron-based signature auto-rotater. I had written this dead-simple script a while ago to rotate my signature file names every 5 minutes, so essentially every time I sent an email I'd have a different/random sig. Not too useful for business communication, but great for my personal box.

Anyways, Gmail obviously doesn't do this by default, but I managed to get it working with a little bit of custom javascript code via GreaseMonkey in VERY little time... even considering the nasty size (depth) of Gmail's html tree (navigating this with the DOM inspector actually took more time than creating the script).

I'll post a link/the source once I've polished it - at the moment I just have a couple signatures hard-coded in that it chooses from, but I'll add a basic interface for managing signatures as well as post it to userscripts.org and/or SourceForge shortly...
