Great plugin but unfortunately it stopped working with TB Supernova 115.1.1
This review is for a previous version of the add-on (0.12.5).Thanks for review! It does work but not all features are available in v115. You can put blame on TB for removing bunch of stuff in v115. Here is more information:
