I am trying to build a JupyterLab extension to add a new Panel to the Left Area. I tried to take inspiration from the celltags extension but I soon realized that it is based on the
INotebookTools interface that already provides by itself a Panel with some controls to manage the cell state.
I would like to start from a new blank custom left Panel, where I can add React Components from scratch and do things like setting my own custom icon beside the ones of the file browse, command palette, open tabs panel etc…
Is there any example out there that does something similar? Any advice or help would be very appreciated.
Thank you very much.
