It would be amazing to have the 'Add Element', 'Pages' and 'Navigator' panel to be moveable, or dockable on the right side of the screen (just to the left of the button/style/interactions' panel).

It would be much less mouse movement from one side of the screen to the other, when editing styles or interactions. Meaning a person could click an element in the design the navigator window, then within very short physical distance, be able to begin setting styles and interactions.

As it stands, having to go from the far left of the page to the far right of the page is a lot of screen realestate to navigate over.
