This has probably been suggested many times, but the "html editor" inside Libronix/Logos is awful. Even this editor that I am using to write this post is better. For a tool with the high calibur of Logos Bible Software, I would think a high-quality editor would be a given.
For the developers, you could check out Aspose.Words, an embeddable .Net replacement for Microsoft Word, which doesn't rely on Microsoft Office at all.
