Custom front-end extensions

This describes the basic steps to write a TypeScript extension for the Jupyter notebook front-end. This allows you to customize the behaviour of the various pages like the dashboard, the notebook, or the text editor.

Starting with Notebook 7, front-end extensions for the notebook can be developed as prebuilt JupyterLab extensions.

This means Notebook 7 is able to reuse many of the existing extensions from the JupyterLab ecosystem as is.
