I often run long calculations. I start them going and close the tab where it's running. If it's going to run for a day, there's no reason to have the clutter of the tab there all day, especially since if I click on it, I might mess up the calculation some how.
When I see the list of my notebooks, I see (running) if it is still actually running AND also if it has finished running and the program is simply open but not doing anything. So, I have to open it every once in a while to see if it's finished. Is there some way to figure out the difference?
