Great potential
Logline allows the user the freedom to not think about which keys to hit to go to the next element in the screenplay. They just type following the simple rules for writing in the .fountain markup language. It is very enjoyable method of writing screenplays. It allows the writer to focus more on what is being written and less on formatting. Currently it does not support .fountain 1.1 but I am sure it will soon. Although it just came out and is a 1.o release; it is already my favorite screenwriting app.
