I'm just getting started with Booktype Pro (the free hosted account for the moment) and I'm starting to play with custom CSS. The only problem is that the only place I can see to enter it is for the existing Publish types, which are all PDF (Book, Lulu, Screen), EPUB/Mobi, or .odt. What I'm not seeing is a way to preview my book quickly in HTML. The FAQ and the manual claim that HTML export is available, but I can't see where.
The closest is the View Draft, but that's (a) almost entirely unreadable due to the draft watermark behind the text and (b) not accessible for CSS styling that I can see.
My goal is to be able to preview a chapter or the entire book in a new tab of the Web browser so I can see if custom styling has been applied appropriately.
