Discourse theme component simplifying the category list (the standard styles, not boxed) by removing the "X / week" column. I think this column is useless and only distracts users. If for whatever reason you want to estimate how active a category is (which probably doesn’t happen often, and mostly useful for admins), you can just look at the dates in the Latest column, or open it and check some topics.
