I'm going to try to be as clear as I can with this. I have one monitor with no room for two. When I undock the PRV for example, and wish to move it up in front of my face, there is that annoying non-optional venus fly trap hot spot that thou mustn't slide your undocked window  near or shlooop! into the dock it goes again. It occupies a good third of the interface and I just hate it. Frankly I'm annoyed with skylight but we're not getting the pre X1 MDI back so I don't beat that drum.
