I wish it were easier to quickly shift between saved windows by having the icons representing said windows more distinctive in the left sidebar. Right now they are very small and it is hard to tell which window is winch until you either hover on the icons and wait for a teeny tiny popup icon with the window's name, or you click the down arow to the right, which triggers the popup with the tabs and saved windows.
The buttons should be made more distinctive by allowing the user to choose an icon to represent each window, instead of the generic Window icon currently used.
Also, I would prefer that popup window to present itself upon mouseover instead of needing the down arrow to be clicked. That would make window swiching much more fluid.
Prefereably, I think that that row of tiny window icons should expand into something similar to that popup upon mousover.
