Translations:Dolphin/File Management/49/en
In some versions of Dolphin, the header of each panel contains two buttons. The button near to the caption undocks the panel. This makes the panel an independent window which "floats" above Dolphin. The window is still combined with Dolphin and cannot be displayed without Dolphin and cannot for example be minimized like normal windows. By clicking the button again the panel is docked again. The second button closes the panel.
