I'd really like it if we could save sets of themes. I tend to load lots of leader name themes, with percentages set to get the proper blend of cultures for whatever empire I'm running, but adding fifteen or so name themes and setting the percentages appropriately when I start a new game is annoying. Plus the fact that all your initial leaders are from a single name set, with the new themes only kicking in for new recruits is kinda annoying too.
