When developing some new code (eg. a function to analyse something) I usually make a .m and .nb file. The code goes in to .m is then called from the .nb.

But sometimes I forget to run the package after saving and then spend some time wondering why my code changes don't have the desired effect.

Is there a way to run a package automatically after it's saved?

Basically I would like that when I press [Ctrl]+S the package is saved and that the effect of this button being pressed is achieved.

Currently I put Import["MyPackage.m"] at the top of the evaluation cell I'm currently working on in the notebook. Perhaps I could also abuse $Pre for this, but then the package would get imported on every cell evaluation (which is a bit needles).
