I have this installed: https://github.com/deshaw/jupyterlab-execute-time
While the cell runs it displays Execution started at 2022-09-20 16:57:19
So you can calculate how long the cell is running by looking at the wall clock.
However its not exactly convenient especially if run time is hours.
Is there a plugin for JupyterLab which displays actual running time once a second for example or even minute would be nice?
Or share an idea how to implement it in a custom plugin..
