Great concept, but fatally flawed on my machine Rated 3 out of 5 stars
I really like the idea, and I love having my tabs running down the right side of my browser and the float over expansion of the tabs - super useful, and very cool. Unfortunately, for whatever reason, my tabs run off the bottom of my screen and there is no way to open a new tab. Basically, I can't use it, though I am really hoping this gets solved. I'm still giving it three stars 'cause the bones are awesome - just needs some filling out.
PS: doesn't seem to work properly with fab-tabs either - no distinction between active and other tabs in my attempt.
