Sorry for the quick turnaround here…
Building on the quick export functionality in the last release, this one now allows you to do a ‘quick load’ on a world. In quick load mode you can’t edit any of the individual blocks that make up your ship (this will become more important once I implement modular building) but you can import / export and save much, much quicker than when doing a full load. So you can quick load a world, clone a ship (I tested with the 2000+ block big red ship) and save the world again in a matter of seconds.
