If you select any of the planet names, the top-left label in the display is updated and both the Center and GoTo buttons will take you to that planet.
If you select "Sun", however, nothing happens. The label isn't updated and the Center and GoTo buttons do nothing, althogh "Travelling" appears briefly at the lower right. (Double-clicking it does minimize or expand the list of planetary objects.)
It'd be really nice if "Sun" were changed to be the name of the star you're visiting and if selecting it would make it possible to Center and GoTo it. Opening up the GoTo window and typing in the name of the star can be awkward, especially if you can't spell it
