Apps that make life a little easier with designing games, movies etc.?

had a quick interesting question-
is there software out there to help better organize a game project and its ideas? i thought pilky was working on something like that some time ago, but i can't seem to find anything like that now and i know full well i've seen it. it could at used for movie scripts and perhaps book writing as well.
any links, thoughts, or ideas?

Mori, SubEthaEdit, some mind map program. Pencil & paper and a file.

Works for me

Writer's DreamKit isn't too bad. It helps you organize and understand basic story-building concepts.

I use an app called Notebook.

Really useful, and not just for game development.
