I'm considering being able to toggle modules on and off, I've noticed sometimes it's helpful to add a module before you find the power for it, but doing so can end up disrupting your other systems and really cripple you. Being able to add a module but turn it off would be good, possibly even in battle as well.
In case it's not clear, the enemy ships are all other players. I realize now that's not really called out in-game. I think that will become more interesting when I add in things like leader boards and a tournament mode.
