The shortcuts now always drive the prompter, the script pane locks so the space bar means play, the count-in is yours to set, and the speed range reaches far below one line a second, which is where most speaking actually sits.
If the person who should be starting the script is standing at the camera rather than sitting at the desk, they can now drive it from a phone. No sign-in, and it works alongside the desk rather than taking it over.
Scripts can be filed by client or shoot, the search box reads the words inside every script rather than just the titles, and Pro can now actually be bought from a real account page.
