I was wondering if there could be an option to pack your spine assets and also the spine file.
So spine collects all images used in the spine build, but discards unused assets.
Folder should contain:
x - amount of assets folders *for each skeleton used*
Master Spine file
This would be helpful with passing folders between artists working on the same project. And when passing assets to devs who request assets for their own packer.
Just for conveniences
