There is a desktop app for screenwriting called Logline. These apps which there are are surplus of are like the Swiss Army knife off typewriters. Not only do they format a screenplay by facilitating invention tabs, they also save your work. I have yet to come up wit a good filling system, but my eyes are worse for wear when I start social media-ing at night. Everything is a blur and I can only guess I'm pressing the right button on the keyboard. Thanks good for swipe typing.
