Insert from File allows us to import views from another project, views like schedules, drafting views or even sheets that contain either. It is biased toward RVT files though.
It would be handy if it we less biased, enough to include RTE (Revit templates) too. Since we probably have standard stuff set up there anyway. Doing so would allow me to acquire a view from a template file instead of having to first save one as a new project or find another project that is already available in a project folder elsewhere.
