Option to focus on single window

I would like to use this extension like "tree style tabs" of firefox:

There, you save about 40px of horizontal screen space by listing only the tabs of the current window. It could be simply done by giving the option to hide the "session" and "window" tabs. Then the element far left will be the first open tab.

We all wait for a Chrome team to make available for extensions author possibility to place own extensions in a real sidebar which is a part of the native window. 

When this will be done then of course such sidebar will contain only the tabs of the current window, as you propose. For a global Desktop sidebar I think this is not a good idea, in the end this is a list of all windows, it is important to show the titles.
