Hi, the RhinoCommon API is different between Rhino 8 and Rhino 7. They both use the identical Folder “Libraries” for custom plugins. How can I define a different one for Rhino 8? We want to be able to switch between Rhino 7 and Rhino 8.

Hi,  
we still have the problem with identical Grasshopper Folders between Rhino 7 and Rhino 8, which makes upgrading to Rhino 8 Grasshopper difficult, having the necessity to be productive with Rhino 7 at the same time. Now, we have the problem that certain plugins work only under Rhino 7 Grasshopper. Updating and testing Rhino 8 messes up Rhino 7 Grasshopper infrastructure, because they are sharing the same special folders for plugins. Is there anybody, who is involved into this? How can we handle Rhino 7 and Rhino 8 at the same time, with different plugin versions installed?
