    Although Manuskript looks great for novels, as far as I can tell from their features list, it does not support screenplay formatting, which is one of the main things you'd want if you're coming from Celtx.

    PERFECT! I love this app, you just need to fill the questions and click on next, ex : Title and metadata > Summary in 1 sentence > Summary in 1 paragraph > Full summary > Character profile > Plots profiles > Worlds characters > Outline > Editor. And you have a lot of other features.

    This is a cool tool for creating and organizing ideas and stories for whatever you're writing, but it doesn't really do what Celtx does, which is writing in screenplay format.
