Idealy, I'd like to see something where we can have one saved template and switch between that one and your current one.
That way, you can full build for a Science vessel AND have a Escort build. This lets you take better advantage of multiple ship classes and still requires you to know some one else who flies the 3rd ship type.
And yes, I borrowed the idea from wow. Probably the only innovation to come from that game... if you can call it that.
