Fences is overall great.  There one glaring usability flaw.. that is if you set up any folder view portal and navigate through them.  the 'back' or 'up' arrow in the title is EXTREMELY annoying in that it moves position depending on the title (folder name).  This seems like a very basic element to define and fix.  If the designers of Fences provide a feature but make it so cumbersome to use...then it is not really a feature and adds nothing to the application.  In order to drastically improve the user experience of this option the following should be supported.  1) the arrow does not change positions in the title bar...seems obvious!, 2) a shortcut key should be enabled for the arrow (back), 3) the windows 'back' mouse action should also work for this fences 'arrow' option.  This is all basic windows functionality and is glaringly absent from Fences.
