It would be nice if when quitting mGalaxy, I could choose to either shutdown or quit to desktop a that point, rather than having to change an option in the preferences screen, and then later have to remember to change the option back.
Perhaps the preferences screen could have a few flags:
[ Show Quit button ]
[ Show Reboot button ]
[ Show Shutdown button ]
[ Show Confirmation dialog ]
That way, I could easily choose which buttons to display. (If none are selected, you get Quit with Confirmation by default).
