Inline Search from IE Forge is a must have utility for Internet Explorer. It gives new FireFox-like inline search UI to IE and does find as you type. Find has also been a feature I haven't liked in IE. I can never figure out what it highlighted on the page! And the modal UI is annoying.

Thanks to Omar for helping me find this again. I'd reformatted my machine with Vista and lost it. I couldn't remember where I installed it, and was missing it every day!
