The irony is that even though there are more features, Linden Labs also REMOVED some of the BEST features of the UI like permissions setting. Before Viewer 2 you could highlight a whole bunch of objects and then right click them and select "Properties" which would open a window and let you systematically set permissions on the highlighted list of objects so you wouldn't have to individually open the properties for each object or script. It was relatively efficient to set permissions on multiple objects this way. Now not only is the viewer slower, but I need to individually set the permissions of every object by opening and closing a new window. It's incredibly tedious and a complete waste of time.
