Is there a plugin or setting in Atom to achieve this very useful feature?
When you click closing tag of an HTML element which code exceeds your editor height, the matching opening tag pops up on top of editor viewport in sticky tooltip manner, to show you which tag are you dealing with and helping you to manage with it’s siblings and parents. Same happens when you click closing brace of function, class or statement in JS and other such languages.
I remember this feature from NetBeans and I really hope it exists in Atom too. Closest to it is Selection > Select Inside Brackets, but feature such as I described would be much more useful with long structures.
