Every time you edit and save a post the page will be reloaded. That means all scroll positions will be resetted. 
Not really UX friendly.
This plugin recovers the old scroll position in your Editor after saving. Either HTML or visual editor.
Sounds pretty good? Install now!

Usually after we set up a basic theme, we miss a scroll to top icon with a functionality of scrollTop after a single click. 
This plugin will help you about this.. Just Install it and enjoy.
