Whilst many people have opposed the decision, the navigation menu interface was forced into the Customizer.
As there are many people who don’t have to time to explain this to all existing clients, this plugin simply removes the menu panel/section from the Customizer.
We support this plugin exclusively through <a href="https://github.com/senlin/so-customizer-hide-menu/issues" rel="nofollow ugc">Github</a>. Therefore, if you have any questions, need help and/or want to make a feature request, please open an issue over at Github.
