I’ve bounced around through the selection of writing software, and recently exported an Amazon ebook e-manuscript from Word to Jutoh (due to Word’s messy ebook export tendencies, plus frankly I can’t stand Word).
Jutoh is very effective and easy to use in compiling ebooks, but it’s book prep capabilities–in contrast with Scrivener–are a bit weak. I’ve heard that Scrivener can be used to output ebooks, but (and don’t kill me for saying this) I’ve also heard that creating/compiling ebooks is not exactly Scrivener’s strength. 
Naturally, seeking the best of all worlds, I’m considering using Scrivener to prep the book, then run it through Jutoh to create the final Amazon-ready product. Have any of you had experience with this?
Also has anyone had any experience and luck using Scrivener to create a book through CreateSpace?
Thanks all, for your patience, assistance, and understanding.
