Great. Based on the response [Is customization of the JupyterLab file browser possible?](https://discourse.jupyter.org/t/is-customization-of-the-jupyterlab-file-browser-possible/1978) it sounds like this is technically feasible. Can I ask for some hints on the direction, if possible:

- Can you point me to the simplest example of a jupyterlab extension you can think of that we could use as a template? i.e. no themes or UI elements required.
- Any examples you can think of that show how to run a shell command from within a jupyterhub extension.
- Any thoughts on the naming of the menu items for this that would be intuitive for the typical nbgitpuller users? How about:
  - “Update Modified Notebooks” = `git pull`
  - “Undo Local Changes” = `git reset --hard HEAD`
  - “Replace all Notebooks with Latest” = `git fetch; git reset --hard origin/master`
  - I think there could be equivalent functions for a single file (e.g. `git checkout -- filename`)
