1- When I duplicate a part, the duplicated part is inserted before the part I want to duplicate. It is better to add the duplicated part after and not before.
2- Similar behavior when you drag&drop a layer from MEDIA BAY. The layer is inserted at the beginning. Idem for loading a song. (maybe there is other way to have this behavior, I did not tested all the ways).
3- When I duplicate a part with Shared instrument, sometimes the Shared instrument is well duplicated, sometimes no… I don’t know how to reproduce exactly…
