Suggestion: running clock in cell

[Peter230655]

I only used my iPad with Carnets Plus to run Python, until I retired 5 months ago and bought a windows PC.
In my PC the Jupyter Notes cells show a clock at the left bottom of each cell. When you run the cell, this clock shows how long the cell has been running. It stops when the cell has finished.
This is nothing important, just a nice little feature.
If you can add it to Carnets PLus without much effort it would be nice - otherwise do not do it.
Thanks!
