I've been working on improving the fleet movement logic and I think some good progress has been made so far.

Above, you can see I've got a fleet moving between Gora and Josius. You can now select in-flight fleets and get a summary of where they're going, how long they'll take and so on. The interface is pretty basic, but I think it makes sense and provides just enough info that you can see what's happening at a glance.

Another thing to note is that I've started using this sprite library from the game "Tyrian" for my ships (and also buildings, not shown here). As before, the sprites and graphics are only place-holders for now, but I like this library because it's got plenty of variety while still providing me with a coherent set of images.

Here you can see where I've got a star selected. You can now view both the planets and fleets around the star by switching between the two tabs. I'm also considering doing away with the tabs and just having a single list with both planets and fleets, but we'll see how that goes.

Another thing I want to tidy up is what's happening on the right there. Those two enormous buttons are taking up quite a lot of space and the real estate could be put to better use for something else. I'm not entirely sure what at this stage, perhaps I could just divide the bottom section into three and have planets and fleets listed side-by-side with the two extra buttons down the right somehow.

Anyway, that's pretty much it for today. Fleet movement is a pretty important mechanic in the game, though, so it's important that I spend time making sure it's as close to perfect as possible.
