Add a "Start Jupyter" button

[jlperla]

I cannot tell you how often I go to a repository in Atom and then drop to the terminal to type jupyter lab in that directory.

A simple but useful tool would be for the language-weave extension to have a "Jupyter" button that does exactly that. Start a terminal in that directory and executes jupyter. You could give it a simple configuration option (e.g. jupyter command defaults to jupyter lab but let the user put in the full path, etc.)

Just to be clear: this isn't really a weave specific thing. It might be a better general feature for Atom directly.
