Preferred/Disliked ad categories
I would really like it if ads were categorized based on content; I love seeing ads for things like pizza and restaurants, but I HATE having to sit through an unskippable ad for a horror movie/show. If ads were categorized, there could be a section in Twitch options where I could move different tags into "show me more" and "show me less" status based on what I do or don't want to see.

It could be like the like and dislike function from the ads for bits thing.
