I really like this concept, very much. It seems like a "Dock" for web pages. I find myself opening up the same page twice in a tab all the time throughout the day, since my default move once I can't easily find a tab is to open up a new one. After a few hours I have about 40 tabs open, only a few of which I have clicked away from and then re-used, and I find myself tempted to close all of them rather than curate them. We should never open two tab for the same web page, and your solution here seems to prevent that. Nice job - I hope to see it gain some steam.
