1.) I like this one alot. We'll try and squeeze it in 
2.) This was discussed when we first decided to take the leap from suns to solar systems on the map, and we decided that it'd be a case of realism being less fun...imagine playing a game on a gigantic map where the map visually never stayed the same. It'd get confusing pretty fast...plus if there was a ship where a planet should move, where would the ship go? All kinds of little oddities like this made us agree on the currect system.
3.) Perhaps this can make it in to an expansion pack, but unfortunatly there'd be alot of code tweaking and interface modification to account for this. Plus we'd probably want to add some techs to counter this later in the game. I think it could be a cool idea, but I don't think we'd have the time to properly implement it at this point. 
4.) You can start reporting typos now.
Great suggestions though! Keep em coming and hopefuly we can get some in before the game goes gold!
