Add the ability to utilizing existing projects in new projects

[jordanroga]

Is your feature request related to a problem? Please describe.
Sometimes I like getting started on new diagrams using the "Samples" button. This is not because of a lack of familiarity with the syntax, but because it's easy to get started with something already in place. This would be magnified 10-fold if I could import existing diagrams I've already made as well.

Describe the solution you'd like
If there was a button, perhaps before the Samples button, which had "Existing Projects" or something similar and could similarly templatize every project I've previously created, it would enable a lot more consistency in certain things and better enable more simplified diagrams (with linking between them.

Describe alternatives you've considered
I currently wind up going back and forth between diagrams to do this. A maybe better alternative could be some kind of copy functionality when selecting a diagram which would create a new diagram from an existing one as a copy of it, "Diagram 1 (copy)".

Thanks!

This is good idea and we should add a way to create a new diagram from an existing one!

@jordanroga FYI, this is in our backlog, and I believe we are tentatively looking at a late spring time frame. I will update here accordingly.
