When viewing the structure tab of a WTPart, I prefer to enable the structure to show CAD Documents, Documents, AML/AVL Objects, and so on. However, the default setting hides these objects. Every time I enter a structure I have to highlight all objects in the structure and enable them by use of the show/hide button. The problem is magnified by the fact that I have to then go and do the same thing with mfg parts that aren't shown until they are enabled at the top level of the structure.
This probably adds upwords of a minute to the simple process of viewing a part structure.
