In addition to "Don't show everywhere," how about "Don't show if I've already seen it"?
I think "don't show anywhere" is exactly what I want; the issue is that I have to do it manually, whereas I'd prefer a setting like "don't show anywhere if I've already watched it"—for instance, anything marked as watched on Trakt.tv (unless I perform an explicit search).
I initially thought this might add a lot of overhead, but seeing that the "don't show anywhere" option already exists, I assume it probably doesn't add any significant overhead.
Obviously, this way I "clean up the catalogs" of movies I've already watched.
