I was initially in favour of this change but maybe you are correct and all the splash screen options should only work when docked.
Want to buy that limited time paint job but not in a station? DENIED! Run for a station!
Want to remap your controls out in the black? DENIED! Should have mapped it before heading out, ya loser!
Want to log in to a different mode? DENIED! Mode changes only in stations.
Change graphics options? DENIED! Choose your graphics in the station and DEAL with it.
Want to log out of the game? DENIED! No logouts unless docked - stock up of caffeine before undocking.
I think that's where you're heading - right?
