Improve Authoring Structure
From an authors point of view Annotum is hell if a lengthy paper needs to be authored.
Personally, I prefer smaller files to edit, an article would consist of many files, i.e. one per section.
The creation of multiple input windows for the body text could be such a solution to work with small sections of text (the same principle as Appendixes are added in Annotum)
