Really the most minor thing.

I find that the best way to level up once you're done with the story missions is to go through them all again on the higher difficulty, which of course means cut scenes that you can't skip (even though the music is amazing and damn it's beautiful).

So I spend my time reviewing my gear and dismantling unseemly items. I at first thought that I wasn't getting anything in return, but I noticed that my total glimmer still increases.

So basically during cutscenes they allow you to interact with the pause menu but they have hidden whatever layer they display items you've received on.
