Firefox 4 will sport Panorama, an awesome tab management system originally dubbed Tab Candy. A proof of concept search interface for Panorama demonstration looks like the perfect thing for those with a lot of web stuff going at once.
Watch the video to see how it's done. You start typing, and any tab with a name, or contents, matching what you've typed is highlighted, and then easy to pull up with an Enter press or a click. It's a great extension of Tab Candy/Panorama, and I hope it makes it into Firefox 4's final release.
