Targets for jumps between systems, naming them, sending that data to the server, interface elements, reworking those interface elements, plotting a course to jump corridors, a new lighting model, finally getting a star to work as a light source (it isn't as simple as it may seem; the basic approach simply fails over large distances), orienting the ship along the thrust vector, and handling jumps on the client.
Still to do: handle jumps on the server, fix remaining issues in flight processing, and load and unload cargo.
After that, we can start. I should manage it within a few days. Cargo is an easy task, as is the jump on the server. The hardest part is removing the problems that have appeared in the flight handler. I fixed about half of them today, but not all.
