I find this handy in Chrome occasionally. Just confirms that BeOS had the right windowing features all along.

Two more OS-level windowing features I'd like to see in browsers:

- OS X like Expose that shows a preview of all tabs for a window. That would help me find a tab visually.

- A command to override the meaning of fullscreen to take over the whole tab, rather than be truly fullscreen. That would let me use other window management features with maximum video size within the window.
