"Suppressed from latest" category vs. "muted" category. What is the difference?

I installed this plugin at GitHub - discourse/discourse-categories-suppressed · GitHub but it has some problems as follows:

  1. The Categories (sub) I selected it does not remove from the categories: Top, Hot… (attached image)

  2. Can you add a function to prevent these selected Categories from uploading images in the article?

I really hope to update and upgrade these 2 functions.
