Indeed this changes in Blender 4.0 and Wayne mentions in the video that it would be redesigned, so I guess this is it. From what I can see bone collection more or less combines bone groups and bone layers in a way that makes more sense. Before you would group bones, but the visibility in the layers. Now everything is in one control. What seems to be more substantial are changing the bone color. Bone collection does not seem to have a color attribute anymore. Might be too early and still a lot to cover in the course, but is there any way to change the color for all bones in a collection?
