This works for removing Editor and Media section for example. But I do not want to remove those. I am trying to remove Blog and Content sections as you can see below.
To remove the ‘Blog’ and ‘Content’ menu items, delete their corresponding blueprint files in the app/blueprints directory. After doing so, run php artisan cache:clear to apply the changes.
Also, the demo plugin now distributes its blueprints in the actual theme directory (not in the app directory anymore). Switching to a new theme, or creating a blank theme, will completely remove all the blueprints and their menu items.
