How does your tool handle cross-references to #include'd pages? I have some home-grown tools that basically use a C++ preprocessor to assemble one big Markdown file from per-chapter or per-section chunks. What I struggle with (to do elegantly) is having robust cross-references, and to keep header levels consistent (e.g. when you include a section that itself has headers inside a h1 or inside a h2, you'd want the section's headers to become h2 or h3, respectively).

Do you have any support for reviewing, in a way similar to Word's 'Review' (comments and tracking addition deletions)? Using version control and branches is not OK, because non-software people cannot wrap their heads around it (just getting them to write in anything but Word is already a big enough hurdle...)

Do you have a proposed workflow to work with formulas? Inline TeX (or LaTeX) is again a no-go, it's too finicky to get right for people who don't have Edit/Compile/Preview Stockholm syndrome (bitter? me? nah). What I'd settle for is a separate file for each formula, and a graphical editor that can edit those files. A somewhat convenient desktop-based editor that'd give an overview of everything would be better (so having some way to start EqualX from your desktop tool would be enough).
