Select the first visible item after loading the next page

Is your feature request related to a problem? Please describe.
I usually use the j key to move the cursor down post by post. When I reach the last post of the page, I press the n key to reach the next page. Now the last post on the new page is selected and there is no easy way to select the first post on that page.

Describe the solution you'd like
Change the default behavior of the next page command (key n), so that the first visible post/comment gets selected whenever a new page is requested.

Describe alternatives you've considered
Alternatively, one could define new commands to achieve the behavior described above. But in my opinion that should be the default behavior.
