Add a button or function key to re-run the last model run
This would speed up the process of model calibration, where I would be adjusting a pipe roughness, PRV or PS control and run the model after each adjustment. Instead of opening the run schedule and clicking run and then ok, a run button or function key would speed this up.

right-click on the run and re-run → the software is going to ask you if you want to use the latest network/control.

In 2021.9 we added a new solution to this workflow to simplify the process.
Right click on the Run Object and select "Commit Changes and Re-run".
This allows you to commit changes to the network and/or control and automatically execute the run afterwards in just one click. -

I think the OP meant re-run without waiting (quite a while) for the (unnecessary) "do you want to re-run", then waiting (quite a while) for the "when do you want to run" (always now). Brilliant would be if it took you back to the last item you changed (or graphed) so you can see the effect, rather than having to navigate to it each time. We all do this thousands of times and it would really help.
