In File menu, add an option to 'Save & Close' in one step.
In File menu, add an option to 'Save & Close' with one click. Currently, one has to either:
Click on 'Save', then click on 'Close', OR
Click on 'Close', and then answer the question "Do you want to save the changes etc etc." with another click.
With the option to 'Save & Close', this would be done with one initial click.
Multiplied by a million files being 'Save(d)' and 'Close(d)' around the world every day, that's a lot of clicks!
