In terms of autosave, I would suggest an option which autosaves after x amount of clicks on any of the time forward buttons. That way the game either autosaves after 20 (or whatever number) times clicking the 30 day forward, or it autosaves after 20 times clicking on the 5 sec forward. Gives a little more savety when doing a looong battle, and not being annoying autosaving if you just click around making notes, designing ships or whatever.
