The sidebar is gone. Sidebar gadgets are now free-floating entities on the desktop. Much nicer way of doing things.
Noooo! What if somebody -likes- the old behaviour? I have the sidebar set to 'always on top' so it acts like the taskbar, on the right side of the screen. I have a widescreen monitor so it's not like it takes up -any- space at all... is the option still there to do that?
