A rather small suggestion, can you make officer updates two separate ones? For example, I have a literal mountain of ground commanders and naval officers, the only guys actually doing anything are scientists and civilian admins. I regularly get a MASSIVE amount of resign spam, several times it was 200+ messages, and I want to see the actual information, like Generic Amazing Scientist's skills increasing instead of people resigning.
Simply, I ask that you splice "Officer Updates" to several messages, like when an officer's skills increase or similar, I.E. there would be "Officer Resigned" and "Officer Skill" etc. etc.
A less likely suggestion, Political Reliability should have a separate message too. I don't really care if an officer has made friends with a powerful cutthroat businessman and his political reliability increased.
