OK, other than setting a Rally Point for a Shipyard, is there any way to control the hex that a Shipyard launches ships into? I often have these things stuck next to asteroid fields that the shipyard wants to eject them into, screwing me out of my first turn's movement.
Try blocking the tiles that you don't want the shipyard launching ships into with a space station or planet. That's the only way I know of to adjust launch direction without messing around with rally points. Won't work for avoiding asteroid fields adjacent to the shipyard, of course.
Speaking of, I really wish pathing would go through rather than around friendly space stations and planets, especially if they're at a point which makes the way around them a bit long (e.g. in between two planets, or in a gap between nebulae or dust clouds). That might be a problem with the aggressive automatic fleet formation behavior the developers put in place, though, given that anything that stops moving on the same tile that some other thing is present on jumps into a fleet with that other thing.
