I wish I could get a page count in wrap view

It would be nice to know how many pages my first act is running without having to export it.

Open the whole act as a Scrivenings session; the page count will appear in the footer. If your formatting in the editor is close to what you’ll use for the compile (and I imagine for most scriptwriters it is, but I say that having only ever written one script in Scrivener), then you’ll get a fairly accurate count.
