You can easily manage the database file with small Python scripts or via various tools. Yes you can keep the operator instance by keeping the operator running, in this case you would need to start a modal operator, then use some action to trigger it (think the knife tool - it stays running and but act's when the mouse is dragged). More than 83 million people use GitHub to discover, fork, and contribute to over 200 million projects. It is possible to store the state of a Python object in the form of byte stream directly to a file, or memory stream and retrieve to its original state. For these cases, Python provides three persistent storage modules that use special binary files to store objects more like the way they are represented in memory. It's also pretty easy to pick up and use. Namespace/Package Name: molnsutil . Create an empty list as man.
