I would like to submit for consideration an "annotation-only" mode for Revit.
Simply, you would click a button in the annotation tab, and you would enter a screen similar to that for crop region where the floor plan is greyed out and inaccessible. In this view, you can annotate as usual using all the Revit commands. The benefit of this "annotation-only" mode is that you could select and delete annotations without affecting the underlying geometry of Revit. This would give allow users to annotate views in a single maneuver without fear of destroying any geometries.
