It is really good for performance if there as an option to find and list used and unused features, and then the ability to deactivate all unused features.
Mainly after the setup of a website is complete, we can do this to have the possible performance.
The current features in performance not easy to use, because there is many items that we don't know them, also there is no automatic system to show which one is not currently used on the website.
Also, it is so good if there is a help page to explain each item.
Kind Regards
