A while back, when working on my Spotlight-style search field, I created a small image modification for iChat which I’ve decided to share. When using groups of contacts in iChat, the headers for each group are a dull gray color. Thanks to OS X’s application bundles, I was able to easily open all the pieces that make up iChat and modify the header images to look like Spotlight results. Why? I just think it looks better. If you think so too, you can get the files and instructions right here.
