Some of the Achievements are interesting, more like mile markers on a trail. Maybe you could go through the long list of achievements and mark the ones you are after and then you are only notified when you hit those marks. As an example, after my first landing I was notified I had joined the 1,000 point club for having over 1,000 perks [who cares.] Or landed a damaged plane, so 'kiss the ground' achievement, [again, who cares.] Now, when I pop the 20th P-51 or whatever the threshold is I would find that interesting.
Just my two cents.
