The latest release allows installation alongside SE. I don't have the time to play through this to ensure it's working as best as it can, so I'd appreciate feedback and save-files for any specific issues.
So far, I can tell that it does a lot of weird things with the Remote View, so there are some inconveniences. If you aren't using Isolation, then you'll have to double-enter the Sandbox because SE does something that undoes our attempt at entering; if you are using Isolation, then you cannot use the Remote View while inside of the Sandbox. AFAICT, there's not much or nothing that I can do within this mod to work around those, so SE will have to adjust to support this mod.
