Thanks phil-Unity For the moment we use NGUI system to handle all our 2D so we are not in the need of rearranging. So thanks for clarify where to find, how to list in Alphabetically order. But I must ask, what happened to the search function? If I search in the Hierarchy View, for any object, select it and close the search. It doesn't expand my GameObjects anymore, so I can't actually see what I have selected. If you have a lot of GameObject nesting or searching for a certain scripts it's impossible to find the one you have searched for in the Hierarchy View! Just a minute later I found a way! If you press "F" it focus on the object in the Hierarchy View!
