I have no clue how feasible this would be in practice, but it would be nice if you could have different "tiers" in blacklist. I use my blacklist to hide things I am just not interested in looking at, and things that make me gag if I even think about it too much. I have to switch my blacklist on and off quite a lot because I do quite a lot of tagging, and it would be nice if there was way to have some of the blacklisted items to not be affected by the toggling.
I got two potential solutions:
1. Blacklist tier that you can toggle on and off the way it is currently, and another tier that would not be affected by the standard toggling, and would require additional steps to toggle off.
2. Blacklist grouping, so you could either put everything in one group and have everything function the way it does now, or make additional groups that would allow toggling different sets of blacklist items separately. (Feels more promising option to me since it's more versatile.)
