Move Highlighter to current screen after mass delete

The Problem

Sometimes when I delete many, many emails, I lose the highlighter. I very often use my keyboard only, so I have to press up or down in order to find the highlighter.

Proposed Solution

Never let the highlighter leave go below or above what is on screen.


This is the highlighter, btw. Not sure what it’s actually called…
