When you have many labels, the list just shows “Label”.
It would be nice if at least part of the Label text would show in the list of overlays.
You’re referring to the edit screen for an Image Overlay block? I’ll file a ticket to add some additional identifying information to each header; labels are easy (can use the user-entered text) but some of the others (bar and image, especially when conditions are applied) are trickier.
FYI, if you are trying to track down a specific overlay element’s configuration panel, you can click on the element in the image overlay block preview on the right, and it will mark that segment as “Selected” in the editor on the left.
Yeah, that’s what I ended up doing.
