I ran into this issue today. It looks like you have a whole other thread on it too. Unfortunately, without this, we can't complete our scripts. I can't share the use case. But, there is a reason why all the major apps support it. Sometimes, you need dual action and dialogue. I'm in a tough spot because I have a deadline and switched to Storyist and would have to quit using it to meet my deadline. . Anyway we could get a quick fix? It seems like you could just highlight dialogue for the left and highlight for the right and just display it properly on print and extend the page to keep the page numbering correct. That what Screenwriter does. While I am at it, I'd love a collaboration version of the app and would pay a monthly fee to use it.
