This interesting, perhaps because it works from a base of mindmapping to a screenplay. The tutorials are probably among the best anywhere. Perhaps Scrivener could go this way - brilliant mix of excellent graphics and screenshots with adequate, friendly text.
Don’t think I would use this app myself (for writing), but it may just appeal to others, so here it is:
From the NovaMind web site.
You can write your complete movie/play/TV script in NovaMind and upon completion, view all the scripts compiled as the one document using the Screenplay Preview before printing. If required, reordering of scripts is easy by using the drag or graft mode to reorder the branches with attached scripts.
NovaMind can also export your scripts into RTF, FCF, PDF and TXT format to be shared or imported into Movie Magic, Final Draft, text edit, Word and many other programs.
The Screenwriting Interface
The beauty of a screenwriting program is that it will format your script while you think of the important things - your script content. NovaMind formats according to movie industry standards for font, margin settings, line spacing, mores, continueds, element standards and page numbering. It’s intuitive interface will cycle through the script elements in logical sequence - action, character name, parenthetical, dialogue, transition, scene etc. By using your return and tab keys NovaMind will progress to the next logical element to follow what you have just typed. Alternatively, function keys have been assigned to each element for quick selection. Text completions save re-typing of character names, scene headings, int/ext. and time of day. All this is in addition to the standard features of NovaMind, which are all included in the screenwriter edition too.
