Evidently, the developers don't use the product at all. There was a request for an auto-scroll function that automatically highlighted a part or assembly in the model tree when selected. This wasn't just to find a part in the tree. That could be done with Find in Browser. It was to allow the selection of features/geometry during operations. EX. origin planes of two parts. In other words, the main reason for the auto-scroll feature is to highlight a part after another part has been selected. This still isn’t possible in Inventor. It should also work for features in part files as well.
