Suggestion: How about adding daily stats for players? Just something simple to track how many sectors we gained/lost in a day, maybe a count of how many of each type of unit we have, how many we added/lost that day, etc.
I could do current stats (say on the GT main page, above/below the general stats) now, but stats about changes would be more extensive. I'd have to add a bunch of historical tracking. So, maybe something for the future.
