@jonas Thanks for the reply. Well... turning off the "playing widget" doesn't solve my problem, because although it makes the metadata go away, it also makes the cover art go away. What I want is to keep the art, but without the metadata. Now, they come and go together.
Let's talk about "playing widget". I don't see this in Clementine. I never noticed it in the Strawberry settings, probably because the meaning of it is unclear. In practical reality, this term seems to refer only to the display of the cover art (and its metadata). How is that a "widget"? To me, a widget is something with some functionality, not just a display. If this term was introduced in Strawberry, I really think it needs to be changed. It is not understandable, at least to average English speakers. Finally, is there any real purpose to turning off this widget/display? It's not replaced by anything else. Either the art is displayed, or it is not. I feel like this is an area where the UI of Strawberry could use some careful thinking-through.
