Don't ask for Restart / Power Off confirmation when not necessary
While doing some kernel testing (lots of reboots) I noticed that rebooting from the system-menu (panel top right menu) requires a lot of clicks.
There used to always be a dialog on the "Power Off..." option because that dialog allowed the user to differentiate between Restart and Power Off. Now that we have separate options for this, I believe that it would be better to only show the dialog if there are other users logged in or any inhibitors are active, IOW do not show the dialog when it will be completely empty, other then saying "The system will Power Off in 60 seconds".
Note that the chance of accidental clicks is small here, because the user first needs to expand the "Power Off / Log Out" menu, indicating that the user is already planning on ending the session one way or the other.
Immediately powering off / rebooting when selected from the system-menu, matches what Windows 10 does, clicking the "Power" option there allows the user to select between "Sleep" "Shutdown" and "Restart" and selecting one of the 3 will immediately execute the selected action without asking for confirmation.
And doing this would also make the behavior of the Power Off and Restart options consistent with the Suspend option which already gets applied immediately when clicked.
We could then also drop the (IMHO not so pretty) "..." which the "Power Off..." and "Restart..." options currently have in their name, which I assume is there to indicate that this will pop-up a dialog.
The goal of this Design Team issue, is to get input from the Design Team on the suggested change, before filing a RFE against gnome-shell to make this change.
