If you read this blog much you know I like subtle stuff and this is right-click subtle. We can already sort the Views portion of the Project Browser so that only views that are Not on Sheets are listed. To see those that are on sheets we just scroll down to the Sheets portion of the Project Browser instead.
Revit 2016 brings us a new feature which allows us to right-click on any view and choose Open Sheet for any view that IS on a sheet.
Naturally if the view you right-click over isn't on a sheet then the choice is disabled.
