No, because when I open a series, if I don't close the first one, when I close the others with Ctrl+W, at a moment Cent activates the tab to its left (the one from where I opened the other tabs). So there is a difference.
For example, having #1 +# 2 + #3 opened, if from #2, I open 3 more tabs that will give #1 + #2 + #4 + #5 + #6 + #3. If I activate the #4 then close the series, it will activate #5 (right), then #6 (right), then #2 (left).
I would like a feature which colors the tabs of a same group (like IE 8 and 9 did) bu it's another story.
