OK, so we don't even know if the concept of issues is in, but if it is I have a few suggestions for new ones
Revanchism - can only be an issue in a country which has a core on another. Can affect any POP regardless of ideology.
Reform - Any potential reform, such as minimum wage, votes for women, health care should be issues
France/Ireland/Any other nation - it would be cool if when you had really bad relations with a neighbouring country, your jingoistic pops could demand a war through the issues mechanism. Maybe this issue could go away once you had beaten them in a war.
