"The current state of affairs in the ebook-building world is not much better. Some print-oriented tools such as Adobe InDesign have been retrofitted to output to ebook format, but the quality of that output is not great. A few writing apps (Pages and Scrivener, to name two) will export to ePub, but their output is also a bit limited and a bit generic. And then there are the open-source tools, such as Sigil, which combine functionality with godawful user interfaces."
