There is an issue with renaming selection groups in the animation section. When I renamed a selection group it renamed all the imported parts from McMaster-Carr. Now I have to go back to an old version and copy the part numbers for several screws I used. Selection group names should be a separate property line item when looking at the properties dialog for parts. This way, the part names and descriptions can be independent of the animation selection group names, which are likely to be unique to that environment.
