Something I suggested once for the reddit app I used to use that for some reason got downvoted in their sub was an option to make the NSFW filter time or location-based.

Everyone of course uses Lemmy differently. Personally I try to keep all of my NSFW content on a separate account, and on my main I pretty much exclusively stick to communities I'm subscribed to, so I don't have to worry about too much crazy shit coming through.

That said, something that's a bit NSFW will sometimes slip by in a normally SFW community, for example, maybe an artsy nude picture will come up in a photograpy community, or a table saw injury that's a bit gory in a woodworking community. Having NSFW maybe automatically turn off during my working hours, or automatically turn on when I'm at home and off when I leave would give me a little peace of mind about those odd things that slip through without me having to remember to specifically turn it off/on.

Not something I'd consider to be a super high priority, but it's something that I'd consider to be useful and I have a hunch some others would as well
