Atlas UI would be enriched if the navigation bar would be closed automatically when clicking on a navigation item to head to that page. If somebody has opened a page it's not necessary for him to still have the menu bar open. To be honest, most users find it annoying when after opening a page the navigation bar doesn't close automatically. Because that would be seen as regular behavior.
There should be at least the possibility of customizing the described behavior.
I have this problem too - this is a bad/non-standard UX design that the hamburger nav doesn't close when someone clicks on a page. It requires the user to click a second time to close the nav just so they can see the page. Anyone find a solution to this yet?
