Last night I uploaded my second vBulletin modification - it alternates row colors in threads, search results, and forum listings. A pretty simple piece of code, but it took me a while to write up a decent set of instructions.
The plugin is downloadable at http://www.vbulletin.org/forum/showthread.php?t=125654.
Not sure how many people have actually downloaded the code, as I've changed the file after a few questions, but it's cool to have a few installs on day number 1.
The idea itself came directly from vbSEO.com - and they apparently have planned for release a more extensive plugin, but for now, I think mine is the only one available.
I searched and searched, but only found other people looking to do the same thing - nobody who had actually accomplished it. Strange - since it turned out to be so simple to implement. I either wanted it more than anyone else, or I happend to have a lucky understanding of how things work internally. I say lucky because I don't know vB that well, just a few key things about it from my previous attempts at learning the product.
Anyhow, I think alternating row colors in vBulletin are cool. It makes certain styles just appear a lot cleaner. I don't know why they don't offer this as an out of the box feature - probably because the requests for similar updates would just turn into never-ending feature creep.
