Thank you for the suggestion. An intriguing idea. However, I would not advise ever ignoring anything under the “Critical” section. As for the “Recommended” section, it’s kind of implicit in the labeling that these could be ignored. You’re free to so in either case since it’s your own site anyway.
I realize you meant you’d like to hide certain recommendations. Just because it’s visible does not mean you must heed the advice 🙂
