Is there a setting that brings about a complete blue background of the line where the selected file resides. At the the moment the blue background is only as long as the name of the file or directory; cf. the attached PNG.
@playful: The Dblclick-action in empty place can be set individually (I set to switch between list- and thumbview), but AFAIK "go to parent" is not enabled by default.
@Sasa You're probably right, don't recall if that's the default.
So for the record in case wervierat is interested, the setting is Prefs / File Displays / Mouse / Double-click on file display BG / Go to Parent, or even better, Run "ListerDoubleClick_UC" which adds cool functionality to shift and ctrl + double-click BG.
