I like to change the settings so that preview windows are opened as new windows instead of new tabs, and then
1. Open 2 separate chrome windows
2. Load project on both
3. Run preview on both
It's still kind of cumbersome. If you're only adjusting and testing code that happens on the peer's end, you can just leave the Host running while you tinker and re-preview the peer repeatedly
C2 runtime doesn't require the host's window to be open, but for some reason C3 does. It would be nice if we could run the Host from a minimized tab again
