I only used subtext beat to develop characters and character lines. But I can't say that it was comfortable. Indeed, the timeline and cause-and-effect relationships are the most important thing. But in the research area, more thoughtful tools are needed, because the creation of script beats is preceded by a large amount of work. Usually, by the beginning of a detailed construction of a story, its structure already exists, the roles of each character in the story, the arcs of characters, their character traits are described and situations where these character traits can manifest themselves are selected, a system of interaction between characters is built. Now I do all this outside of Causality, because it is inconvenient to do such work in it.

No, I haven't seen the documentation for 3.0. Thank you for the link!

The tutorial videos on youtube helped me a lot. Even if you do not know English, you can turn on subtitles with translation. Everything is extremely simple and clear. It is a pity that the tutorial videos are made only for the main features of Causality.

Yes, exporting your script to DOCX is very important. Of all the scripting software I know, Causality is the only one that doesn't know how to export a script to DOCX. Adding and formatting a title page, re-numbering pages or scenes, adding a character bible, removing some special characters, such as (CONT'D) - these tasks become extremely difficult and time-consuming. The PDF script cannot be edited properly. Conversion of a script from a PDF file to the DOCX format does not work completely correctly. Spaces between words may disappear and other problems may arise. As a result, in order to make minor changes to the script formatting at the request of the studio, I have to first check the entire text for errors after converting from PDF to DOCX. It is very uncomfortable. As of today, you do not have the ability to format the script within the program. You won't be able to meet the requirements of all studios and all script editors around the world. In many cases, the final document will still require revision. It seems to me that to solve this problem, it is easier to export the script to DOCX. Sorry for my english
