Active Ongoing Hostilities vs. Computer Opponents

[SurvivalistMerc]

I sometimes save my Dom2 games and come back for more play later. Sometimes I don't remember who I was at war with in what game. Something that would make things much easier for me (and others like me) and should not be so difficult for the devs would be an indicator of which nations the player knows to be at war with which other nations including the player's own.
