    I don't quite follow..? This is commented out because there's more discussion needed about
where the "Compact View" button should actually appear. It doesn't make terrible sense to
put it in the Query Options tray (I'd argue!) so it'll hopefully end up elsewhere. Once that's
in place I'll remove this.
