I'd like to suggest adding width and height properties to AudioCoverArt.
Preferably in a way that determines it when the property is read (to avoid needlessly open files).
Btw, a bit OT, but did you change the sort order in the new beta (11.5.4)?
"_sometext" has always been before alphanumeric names, but now it is at the bottom.
(I didn't feel the need to add yet another thread just for that question).
Is there an option to revert the behavior?
