Much as I disapprove of Word and it's complicated underlayer of kluge programs, the problem for open source software is how to coordinate and document multiple word processing sub-systems to put together a clean, balanced, and powerful word processing performance suite.
Like Eric Raymond's model of the Cathedral and the Bazaar, the problem for open source software is to pull together small parts of a superior system from many independent authors and coordinate the accomplishments into districts and describe what each module does in a way that makes sense to the wide variety of visitors.
For my wife, a very busy fast working touch typist, there needs to be a pushbutton "Word mode" to make the word processor behave keystroke by keystroke just like Word of the Office XP vintage. With her, she always is facing deadlines, writing furiously and always exchanging .doc files.
For me, the problem with Libre Office is I am stuck with a version I downloaded outside of the Ubuntu Debian package system. I have lost track of the re-union of Open Office and Libre Office. Big embarassment for me, I don't have time to straighten it out.
So how can open source free software move away from Word and become the clarity, quality and power leader?
I really like the observation earlier that the office suites need specific development by area experts.
The user documentation for add-in modules needs to be very good. That means OO or LO need a documentation system that can pick up new chapters and new cross references when a additional package is added to the word procesing suite.
I would like a 8-up card module, a mailing list module, a bulk email response tracking module, a wall-poster module, a fill in a scanned blank form module, a Google Docs module, a google blogger editor, a music quoting module, a classical greek quoting module, a school-teacher-class-student-parent database module, an rsync remote mirror and a paragraph checksum integrity module.
Another half of the battle is the suites need good example files. How about identical example files in American English, Dutch, German, French and classical Greek, Japanese, Chinese, Hindi. These language files would model how to set up OO in each of the languages. I would like to see example files of a short book, a term paper, tables, photos, movies, mathematical formulae and music notation with linked audio.
Finally, another area where open source software is lacking is in the conversion from screen image to printed on paper image. There is a point where the WP program dumps data into the printer driver and control and knowledge about sheet size, ink and pixel size is embedded in some unknown place.
