So I must admit I'm a bit of a perfectionist, and I often play missions over and over again until I ace them. Every so often that dialogue box pops up saying "you have failed this mission, blah bah blah...do you want to skip to the next one?" And I always click "never show this again," but it always comes back. Is there any way to make this go away for good? I really wouldn't miss it if I never saw it again.

No, the "never show this again" is only kept until you accept a successful debriefing.

Unfortunately, to add a setting that will allow for "never show this again forever" will require an update to the pilot file, which will not happen until we update to the new pilot file format.  Post a request in the pilot file test build thread in the "Test Build" forum, and I or another coder will take a look at it later.
