Improve documentation for discourse-categories-suppressed

Continuing the discussion from Allow @mention notifications in muted topics?:

Just revisiting this since I’ve been using the discourse-categories-suppressed plugin for a while now. It actually suppresses from Latest, New, and Unread — not just Latest — which makes it really useful for categories that should remain visible but not contribute to any “active” views. It’s probably more widely none that it groups the category below a “Muted categories” dropdown. Also, i have tested what i said on the linked topics about mentions’ coming through on suppressed/but muted categories.

It’s one of the only ways to truly suppress a category without relying on user mutes or hiding the category entirely. Would love to see this get:

  • a checkbox in category settings
  • a proper plugin topic on Meta
  • or even some lightweight documentation.

Right now it’s a bit hidden and underpowered given how useful it can be. Any chance of a write-up or some UI love for it?
