In the previous notebook UIs there was a symbol which appeared after the notebook cell finished running. In the most recent version this was removed and now when you run cells which don't have any output (e.g last line in cell: x = fcn(y)) you don't know if it completed or is still running unless you expand the cell output and see the green checkmark.

Feature Request: If we could add a symbol which is visible when a notebook cell finished running while the cell is in collapsed mode that would be awesome.

For example, we can just move the cell run number ([61]) and the green checkmark outside the collapsable cell so they are always visible.

Thanks!

Current UI Cell Collapsed (no completion symbol)

Current Bottom-of-Cell UI Expanded (completion symbol visible)
