It would be great if there were an option for customizing the position of the sorter tab. I find it works fine, though it would be great to be able to customize its place. I am basically happy with top left of the screen, but it would be useful to be able to place it a centimetre lower. The reason is that many apps open windows in the top left, and I have to move them to click on the red traffic light to close them. If the sorter were not quite in the corner, life would be simpler.
Of course, it may be that the option is there and I have just missed it. I know I could hide the sorter and use a hotkey, but then I have to remember what the hotkey is, and the sorter tray is neat.
