From the very beginning of my downloading the initial Highland release, I’ve used it for much more than screenplay writing. It’s a great place to hammer out the bones of a story, no matter the story’s final form.
Highland 2 takes this use case and runs with it. There are templates for fountain (screenplays, stage plays, multi-cam (for sitcoms) and graphic novels; there is a boatload of markdown templates including film pitch treatments, novels, journals and a lot more; and of course, plain text.
There are tools for working with the document overview, for pushing yourself to write more (goals, etc.). And it exports to .rtf, .fdx (Final Draft) and more.
I’ve hardly touched the surface of what Highland 2 can do, but I have to emphasize that its many capabilities are well organized and presented. I’ve not once felt overwhelmed with (ahem) options.
The app is rock solid. I have not been able to break the beta. I can see it becoming my primary writing app.
