It would be really nice to be able to add the Custom faction to a custom Sovereign in the faction editor instead of having to go into the programming and add it manually. So that when ever you use that Sovereign in the game he has his custom faction automatically unless you change it.
Also when down loading from the MOD screen in the game a custom map it would be nice if it went into the right directory instead of manually doing it in the program in order to see the map on the map list when you hit load.
