Partial Blocking of Users

Let's just say that I don't want to see a post from that specific user in certain channels but want to be able to see their messages elsewhere and still allow them to PM me. Maybe it's because they post constantly post themes of images I don't want to see when I want to see different images.

Partial blocking, similar to muting channels but you could specify users and it collapses their message as if they were blocked but on other channels, their messages will show just fine.
