{{man tip| 1=Changes to Rules are inconspicuous|2=New built-in Rules appear without any fanfare. Plus there are so many of them, grouped in so many subcategories that they may remain concealed.<br />Addons require downloading and installation, so the addon Rules have more visibility than the builtins. Plus they can be searched as a category in the Plugin Manager.}}
