It would be nice to add a view/mode that shows the same lists as the Equipment tab from the in-game Profile, including the filters, so one can more easily check what one forgot to mark as Mastered in FrameHub.
One peculiarity of the Equipment tab is that "Companions" include only beasts (Kubrows, Kavats, ...) , while the "Companions" in the mastery breakdown view includes the beasts but also the Moas, Hounds and Plexus.
Another is that both the "Primary Weapons" and "Secondary Weapons" views include the Kitguns.
