Is there a sensible way of having the Ofelia window shown both on a full screen projector/monitor and at the same time windowed on my laptop sharing space with Pd-gui controls? Im on Mac for this. I was hoping that osx had some built-in feature for this but I at least have not found it. Thanks.

openFrameworks has some examples with two windows. These are located in the examples directory of an OF installation. If it's possible with OF, then it should be possible with Ofelia too.

Not sure....

You might try with the ofelia test version based on OF 0.11.2 that cuinjune compiled here?

I don't know about Ofelia, but you should be able to install a workarround with a screengrabber software. E.g. with OBS studio you it should be possible to grab the ofelia window and bring it to the second screen. Maybe not the best quality solution, but i have used such workarounds where quick and dirty was needed.

Another alternative would be to make an abstraction of the graphic patch and run it in another instance of puredata and send data betwwen thel through osc or share_mem external. Did it once and was working well...

I solved it by having looped interludes where I could adjust and look at the projection. It worked quite OK. A plus is that I was not distracted by the visuals when performing, so the setup made sense in this way too.

But will try some the methods mentioned here next time I perform with this setup. I really like the OF/Ofelia setup, had almost no crashes or oddities happening and I even wasn't that careful. And CPU pressure was quite low too.
