It drives me nuts when I click the X in the upper left corner of the Rhythmbox window and the Launcher Icon disappears but Rhythmbox does not end its process (and keeps playing music).
There used to be a way to change this behavior in 10.04 by disabling the "Status Icon" in the Plugins section of Rhythmbox. But with Unity, there is no status icons anymore--there's Launcher icons.
When I press the X in the window's corner and the Launcher Icon disappears from the Launcher, I want Rhythmbox to be closed (no process running). Anybody know how to configure this?
Far as I can tell, the only way to end the Rhythmbox process is to press CTRL+Q. But this is not consistent across other applications in Ubuntu. ALL other applications respond to ALT+F4 to end the process.
