JerkMuter από Alaric von Teplitz

The main feature is the ability to ignore users' threads, posts, and quotes. You can configure these to be hidden outright, or see a placeholder letting you know that someone's post was muted. The placeholders can be configured with a custom message and colors, as well as optionally display the name of the muted user. Additionally you can enable a "peek" button so that you could temporarily reveal the hidden content without unmuting the user.
