Flatsome menu already has the option to make it sticky with some options on that part. How about adding this awesome option: Notice how the menu disappears when scrolling down and only appears at the top of the page but ALSO appears as soon as you start scrolling back up. I find this feature to be a very cool and useful, as it gives more space for the content as well as easy access to the menu. How about you?
Try to scroll down, and then back up.
