One other thing: -
With this feature disabled, when you single-click click on an album, the album art is highlighted with a white box.
With the feature enabled, clicking on an album causes the white box to appear, but disappear again in the blink of an eye. I don't know whether the intended behaviour is for the box to remain visible until you click on a different album, but if so, that's not happening.
EDIT - Also, I think this latest version is a little less snappy. Clicking on different albums to open the expanded view is basically instant, but clicking to close the view seems slower, like there's a slight delay before it closes. There's also some flicker that I didn't notice previously.
