Three questions

[Vanant 2]

Is there a file where I can modify the way those colour boxes appear surrounding ships? I´d prefer to delete them and only let them appear when a ship is hit or i´m doing a mouse over.

second question, what is that "ghost" ship that always appears in the center of my map, in any system? it´s a bug?

And the last one, What is the purpose of scanners if I can detect any ship on the map anyway? it´s only for targeting?

Thank you
