User Level Collections or Favorite Tagging

For myself I use a collection called “Favorite TV Shows” that I can filter down to the handful of shows that I actually want to follow in my library, but that only works for myself, other users have no way to get the same results because they can’t create collections of their own. I would love to see some way for all users to be able to “tag” things so they can be filtered for their own personal likes. I’ve tried using playlists and smart playlists, but this doesn’t really have the desired results.

Anyone else like this suggestion?
