First off, I think this game has a lot of potential and am very excited to see how it ends up. I only got to play for about 30 minutes last night, and a lot of things I noticed have already been mentioned by other people. One thing that I have not seen been brought up is how far in and out you can zoom during a battle. I would like it if you could zoom far enough out to see the entire map. It would give you a really grand view of what is going on. Also, zooming in closer would be fun to watch a ship get destroyed or fire weapons.
Another function that could be nice is looking the center of the screen to a particular ship. Some times just focusing on a single fight looks neat, but can be hard to keep track of.
