Sector display is top left. It and the planet/ship display could as easily be swapped. And there's plenty of room down the right hand side for more "buttons".

Edit: and I've no problem with movable panels but the main thing IMO is that most screen resolutions (all?) offer more space horizontally than vertically so it make far more sense to use the space at the sides and thereby maximise the view of the system. With the standard view about a qtr of the height of the screen is unavailable to the system map.
