List above updated... very good progress over the last few weeks.
Got loads of little things done, unfortunately a lot of them too small/unplanned to show on the list... :-/
Surface vehicle autopilot basically done & working nicely, just need some code to avoid island structures intelligently.
Was also thinking of making the supply drone a user-pilotable Osprey-like vehicle rather than the surface-based 'box' of the original.
Also thinking I should include an 'easy' Manta control method like the original, with the on-screen cursor simulating joystick deflection. It's currently probably a bit too sim-like for a lot of original CC fans.
