scroll up button

Is your feature request related to a problem? Please describe.
instead of scrolling all the way up ,adding a button that would scroll to directly navbar when someone reaches end of page.

Describe the solution you'd like
a scroll up button

Start by locating the page layout and navbar, then inspect how the page currently handles scrolling. Add a scroll-up button that appears or is usable when someone reaches the end of the page and returns them directly to the navbar; done means the button reliably performs that navigation.
