I switched to this app from another screenwriting app, because I was extremely frustrated with its performance. ScriptsPro is extremely easy to use and everything is formatted perfectly upon export.
A few things prevent this from being a five-star app right now:
1. Importing existing .txt files can be hit-or-miss. I tried importing some scripts from my previous app into ScriptsPro but they would not import. I was forced to start typing one script from scratch.
2. No Landscape Preview Mode: You can type your script in Landscape mode, but when you want to preview your script and flip through its pages, you have to rotate to Portrait Mode. Not a deal-breaker, but a bit inconvenient when you use a Bluetooth keyboard.
3. Preview Mode always defaults to the very beginning of your script. So, if you are reviewing your script and stop to revise something on page 20, as soon as you hit Preview again, you have to start flipping from the title page.
