It would be a lot nicer if we could move our main ship into slot 1.
Mitigating solutions might be:
Allow swapping which ship is docked in a space station.
Instead of switching to the lowest-numbered ship, switch to the most recently used ship that you still have. (This would match a lot of other "sort by last used" mechanics in the game, and in fact would be my a priori guess for how this should work.)
