I've been obsessed with developing ways to make it easier to handle tab overload in the browser without requiring any sort of active "tab management".

I have a working extension that replaces the "new tab" page with a clean view of all open tabs, along with simple ways to search and select which tab to switch to, including search over bookmarks and history. There are also some simple tools to allow for creating and reorganizing tab groups.

I'm very early and looking for feedback from anyone who suffers from tab overwhelm like I do! You can try it out at http://bit.ly/tab-o-magic!
