Save As and then Submit
Right now if you create a lens, then submit it. And then save as, then resubmit it. I believe it overwrites the original lens. It would be nice if this didn't happen, I'm making a few lenses that reuse a lot of models/scripts and don't want to reconfigure the project from scratch every time.
Basically I'm trying to create my own template
Or it would be nice to be able to edit the hierarchy (objects tab) through code. I believe right now its saved in project.data in some serialized format. But if you exposed it via JSON like the proj file, we could reconfigure the project with the things we want programmatically
