rmx Unfortunately, Spine does not have the ability to easily link multiple skeletons in the editor, so if you want to control multiple characters or objects with the same animation in the editor, you have to combine them into one skeleton.
The separate animation section for each skeleton is a reasonable state, since this is the same as the actual skeleton data. Also, since there are many reasons why you may want to display multiple skeletons in the Spine editor, it is not always a good idea to have the animations of multiple skeletons linked together. For example, you may want to animate a character skeleton on top of a background skeleton that has a short looping animation of waving trees and flowers, and then export the combination of these skeletons in video format. In such cases, the length of the character skeleton animation may not match the length of the background skeleton animation, so it is better to keep them separate for easier management.
