I'm trying to set my browser up to look like Netscape 4.x... and I noticed there's a couple of really minor things missing.
The "Search" and "Security" icons.

It's not a huge issue since I can do searches using the URL bar, or set my home page to go to my favorite search engine. I could probably find some way to put the icons in for just myself, but I figured that since the theme's maintainer is still around... it wouldn't hurt to ask. It's just that it's already SO close.
