Comment 43 for bug 114375

I plan to fix this issue in the next few months, based on Lightproof, partially extending the English Lightproof demo with the results of LanguageTool development, too. But I strongly think, with the default settings the proofreader doesn't have to hurt the users any false warning messages. The Grammalecte French grammar checker extension (released a few days ago by its author, Olivier Ronez, athe developer of the French spelling dictionary) also follows this conception. Grammalecte is based on Lightproof: in their grammar rules it uses Hunspell and the installed French Hunspell dictionary for morphological analysis, also it has native Options menu in LibreOffice (see http://www.dicollecte.org/grammalecte/documentation.php).

It seems, Microsoft has also problems with their grammar checker:

"It would be possible to 'dial up the sensitivity' of the Word grammar checker to catch more errors, the company said. However, that could also cause it to flag sentences considered correct in colloquial usage.

That would risk making the tool more intrusive than people want, the company said. In fact, Microsoft dialed down the sensitivity of the grammar checker in certain respects starting in 2002, responding to customer feedback." See http://www.seattlepi.com/business/217802_grammar28.asp
