Even just a little pop out window from the hanger where you can see the last sortie perks would be awesome.
doesnt need to show anything beyond the last flight.
it would be cool if it broke down the percentages of what you attacked and what attacked you.
also perk points for assists should be a thing, they are mostly unused anyway so its not like it would break the game, and it adds to the feeling like i accomplished something even by getting some assists.
i mocked up a super simple drawing of what i mean, it would not need to be very complicated at all to give lots of good info.
and I dont see any real downsides that would hurt the gameplay in any way.
call it a quality of life improvement.\

see attached image.(very quick mockup)
