Arrow to the top of page

Hello everyone.

I was thinking of a small idea, to facilitate navigation on the browser, regardless of the platform, Android, Linux, IOS or Windows.

Would it be possible to add an “arrow”, at the bottom right of the window, as can be seen on some sites, to go back instantly to the top of the page, whatever it is?
In order to quickly go up the news feed or any page, when it is long or when you have “scrolled” too long.

I don’t know if it’s possible to do and I have no idea how long it takes to format this stuff.

Hoping that my suggestion interests you.

See you soon.
Gerald
