Title says it all. Takes a project name and a path prefix and creates a named toolbox, and creates a code-workspace file that causes VS Code to automatically enter that toolbox in the integrated Terminal. There are a few caveats, but there may be some ways to iron them out over time. Check out the Known Issues section of the readme for for details.
Feel free to test it out and submit issues, pull requests, etc.!
