It would be great to have something like pressing "Ctrl" or "Alt" while opening the logout dialog to automatically save the session (the default behavior doesn't save it, which is good) at logout. That way, if you want to set a clean start session (or update it), you can do it pretty quickly without having to go in the preferences, activate session saving, then log out, log in again, disable saving, etc.
