With the addition of the new vault space (extra pages for weapons), has vault navigation been visited? I find it time consuming to switch between the pages by moving the cursor to the top right to change pages. Is it possible to add in D-PAD functionality to switch between pages of the vault (not between categories [L1/R1]; like pages 1/2)? I think it would make the vault experience vastly improved.
tl;dr: Use d-pad while in vault to change between pages (not categories)
