Modifying Jupyter Notebook UI

[srirag21]

Hi, I want to try to modify the UI of jupyter notebook however every time I modify the html files in notebook/templates, it seems like my changes are not registered. I made sure to launch the notebook by chmod +x jupyter-notebook.desktop and doing ./jupyter-notebook.desktop inside of a virtual environment however this approach does not seem to work either. Are there any references to forked repos I could look at that have successfully modified the UI in a manner such that it persists across different launches of the server. I do not want to just modify customs.css as that seems temporary but rather I would like to modify the actual html templates that are being used. Any suggestions?
