The common workflow for me is developing on my laptop, then installing on customers' equipment. This might occur over several days. Before a new project can be imported, however, you must first manually delete each flow, sub-flow, and all node configurations. Optionally, I could shell into a container and delete flow.json, etc.
It would be so nice if there was a menu option to reset NR to factory defaults!
A somewhat related feature that would be nice to have; Before importing a 'check palettes' button would test that all required palettes are already installed, and even better - prompt you to install them automatically if missing!
