Simple & Intuitive
Sometimes you may need to hide/remove a flexible content layout from showing on the front-end of the website, but you would still like to keep it in the back-end in case you need to re-enable that layout again in the future.
Of course you can always just remove the layout, but if it's a complex group of fields with a lot of data, re-creating it later would be a pain. And here the ACF Hide Layout plugin comes into play. It adds a small button with an "eye" icon to easily disable/enable flexible layout content without removing it.
