New release is out, this one improving quality of life and exploring a new layout of attributes for markers, with Translate Stiffness and Rotate Stiffness potentially replacing Pose Stiffness! 
You’re also able to include meshes in your exported .rag files, meaning you no longer need to export and import meshes separately, and not struggle with connecting these back up. It’s swell!
