As cool as this mod is (It's really cool), I noticed that there's no way to rotate the ships. I know, it's not smooth movement like the Archimedes Ships mod, that ships move by jumps, but I feel that being able to rotate the ship you're connected to to face a different direction would be a great way to improve the mod. Maybe by adding another option in the startup procedure pastebin; choosing the direction you want to face, then jumping.
Also, I've noticed that the hyperspace dimension is colored red. This reminded me of the old television show Babylon 5 that aired in the 1980s to 1990s. In the show, hyperspace was also colored red, but was characterized by bolts of energy and swirling entities in the background. If you could do something similar, maybe have lightning strike a certain amount of blocks away from a player or a ship's edges, it would make the mod a great deal more aesthetically pleasing.
