Not a biggee, but if this were possible:
Re shutdown (remember, not tested yet), is there a way of raising the Alt+F4 windows shutdown dialogue?
That way I would get to choose exactly what I want, but more importantly I would have to confirm, so I would be covered in case of mistaken use of shortcut.
Edit/ and I had to disable Hibernate earlier, not working properly, ah well...
Edit #2/ weird side-effect - if I right-click on the script, the shutdown dialogue shows as long as I keep right button pressed
