The ability to select an object, right-click and select either ADD SELECTED (AutoCAD platform) or CREATE SIMILAR (Revit platform) would be a great addition. It would eliminate the need to have to go to the tools menu, select the command, select the style, etc... I envision this working for most items such as city furniture, roads (plan / design), coverage areas, land areas, but nothing that is associated with a data source such as imported SHP files, LandXML data and the like.
