Find and replace for tags in grouped objects
Right click on a grouped object would show the existing tags associated with the items within the group, and give the ability to assign (replace) with the desired tags without having to ungroup the obect and do each item separately. ex: motor 1 start could be replaced with motor 2 start.
Similar to this would be the ability to select a Window/template object and see a report on what tags are referenced in it. Either select or right-click an instance or group anywhere along the Project Browser tree to view the tags referenced in that group. Export or print ability would be a natural progression.
