As the title says, I would like a way to favorite tags, bump a certain tag to the beginning of a search, and use the favorite tags as a whitelist. (bumping is not specifically related to favorites, but it was initially related so I'll keep it here anyways)
For example, if I do a search such as "rating:e order:id_asc bump:hypnosis group_masturbation", it should organize posts by putting all posts with rating:e and group_masturbation AND hypnosis at the beginning by ascending id, then put the rest of the posts that have the first two tags but not hypnosis afterward in the same id_asc order among themselves.
Alternatively, I could search "rating:e order:id_asc fav_tags group_masturbation" to only include posts with rating:e and group_masturbation that also include at least one of the tags in my favorites.
