Please bring back the ability to rename multiple files at the same time by checking multiple part boxes then clicking Actions-->Rename. This feature existed and was heavily used in Windchill versions before 10.1. I can't tell if the feature was intentionally removed, or just stopped showing up. Currently the only way to rename multiple objects is if they happen to be in the same assembly or drawing that you can rename and it collects all related objects. Frequently many objects need to be renamed that may not be related to eachother.
