How do I change the layout to show a single mixer lane with the rest hidden? [SOLVED]

In Kenny Gioia's vid from 2017 (below), using a previous version, he shows how to move the mixer to the side of the screen and hide all but a single channel, which changes to the currently selected track when you click on it in the main window. However, in the newer version I'm using, following his expample, Reaper now appears to stack 3 mixer channels on top of each other in the same space that Kenny was managing to keep just one.

Am I just missing something here or has Reaper change since then?

It's not a deal breaker, but I would prefer to have a larger fader to play with for each channel, if possible.

Rightclick somewhere in empty space in mixer to get mixer context menu and disable "Show multiple rows of tracks (when size permits)", I guess.
