Description of the new feature/enhancement

Sometimes people using the Terminal need to scroll very far up, and read a lot of previous output. They then want to return immediately all the way to the bottom of the terminal, to see the latest output.

Currently: users scroll a lot to get to the bottom of the terminal.

Proposed: when scrolled more than X lines up, a ⬇️ button should appear that scrolls to UI all the way down to the latest output. I'll leave the UI discussion up to you.
