Of course all you did here is more than great! I don't know an English word that could possibly describe how awesome your work is! I'm sure all the users appreciate how close you work with them and how you take any idea into consideration (and actually nearly realize all of them)!
What I just found out now and really liked is, that when you close a window with hibernated tabs, sidewise still keeps them as a "Hibernated" group! Awesome!
