Or support html exported from Word.
Manuscripts imported from Word lose important formatting (like italics). Which is not usable.
Typical HTML files and filtered HTML exports from Word have to be manually edited for Hindenburg to import them due to the tags (meta, style, class, etc.) and characters that aren't supported (em dashes, smart quotes, ellipses, etc.). All of this is wasted effort, and not the job of narration.
Without the capability to accurately represent a manuscript from the author/publisher, this can't be taken seriously as a professional narration product.
