Open Accordance, enable Instant Details, resize it so that it is as high as 4 icons on the left side of Instant Details's pane.
Open any commentary in the Reader mode, press Command+Option+2 twice. Exit Reading mode. Sometimes Instant Details is all over the main Accordance window, sometimes it is ¾ of its height.
I wish Reading mode wouldn't obscure Instant Details pane. It could remain visible. I can close it separately, but it provides useful information when I hover mouse cursor over the links in commentaries.
