I wish that plotbot was equip with a page counter. Many screenwriters need to know the page because it helps us gauge where we are in the movie. The one minute per page rule is big.
Shoot, if your screenplay isn't long, we don't tell you! That's an oversight and I'll fix that soon. As a rule of thumb, you can divide the number of elements you've written by 15 and you'll get an approximate number of pages (the number of elements in your project is visible on your project's homepage).
If your screenplay is long enough, you'll see a dropdown at the top of your screenplay listing your scenes and how many pages each is, and the final entry will show you how long the screenplay is in total.
