1. It is missing some crucial method calls when setting orbit to another body. I believe stock code has them and I added those somewhere into our code too. Possibly this? https://github.com/KSP-RO/ROUtils/blob/75f4c45feb5909d52b5b07222df30e6068873f6f/Source/ROUtils/Utils/HyperEdit_Utilities.cs#L19
2. make it no longer invalidate MM cache when window positions get saved. (this is Setting file invalidates ModuleManager cache (again) #76)
3. Automate the hack gravity workaround for Principia.
