Plex already lists the director and writer or allows filtering by those (some clients seem to no longer display the available information very prominently).
There’s already some existing suggestion to include more staff details (e.g. director of photography / cinematographer or composer/music producer. I suggest you comment/vote in those threads in order to help us avoid distracting or cannibalizing votes.
Unless I’m missing some unique aspect of your suggestion I’ll close this thread as a duplicate / implemented.
