It would be nice to have the ability to hide posts with certain words that may be in the body of the post but not in the tags or content warnings. Unless I'm mistaken, it seems like right now you can only mute certain content warnings or tags which is cool, but it doesn't help if someone doesn't actually tag or CW something, yet posts about it a ton in the actual body of the post.
As an example, I can not have any tags or CWs on my post that is nothing but the word spaghetti copy and pasted 1000 times, and someone with every permutation of the word spaghetti filtered in the settings from CWs and tags and they will still see my post.
Agreed, this would be especially good for long discussions in which no participant is tagging their reblogs. It'd be nice to have the option to filter by regex, too, but I think even basic post body filtering is a pretty important feature.
Bonus feature: the reverse of twitter's 'Trending', to make temporarily avoiding the latest subject of discourse super easy.
THIS is one of the biggest features cohost is missing for me. i'm amazed it didnt occur to me until just reading this.
not everyone is gonna tag their posts 100% effectively, if at all, and the same issue goes for content warnings. content filters would be the perfect "last barrier" to go along tag filters and content warning filters.
