I am a Battle Master with the Martial Adept Feat. My maneuvers I selected for my Feat and my additional Superiority Die do not appear on the "All" tab together.  I instead have to go into my "features & traits" and scroll all the way to the bottom to see them. It would be so much nicer to see my dice usage button and the maneuvers from the feat grouped with the ones from my class. It seems like a possible bug/oversight that they are not grouped together.

Yeah, there are technical limitations preventing it. I'm sure they have it on a list of intended improvements.
