Hi there, currently the spacebar remembers what it did when you last pressed it - so if you press spacebar to see the interior, the next press will be exterior, and so on, regardless of the current reality. But it is possible to zoom in to look inside the ship, and zoom out to get an outside view. So, instead of strictly alternating, IMO the spacebar behavior should first check the CURRENT zoom level (interior or exterior) and switch to the other one. That way if you're in the interior view, and you happen to zoom out using the mouse, the next time you press the spacebar it will bring you to the interior view again, instead of the exterior view (which looks like the button isn't doing anything). Thanks!
