+ Zookeeper's main layout is now persistent from scene to scene: it is saved whenever scene or zookeeper is closed and next time ZK starts the saved layout is loaded. If the layout is modifier in the scene and scene is saved, when the scene loads it has the modified layout.
+ Added an option to reset ZK's window layout through the Views menu

* Fixed error messages is improper layout configuration file is present (with an option to remove it)
+ Added an option to enable layout configuration editing (which is off by default to avoid unnecesary user confusion)
+ Configuration dialog now displays the path of configuration for convenience

* Fixed treeview selection when filters are applied
