Jacrobat is a free open source PDF editor that will support all functionalities of a simple word processor. Advanced functionalities will be added as the project matures.
Could be exactly what I need but it needs page setup feature (with user defined width, height and margins) and unicode support (unicode characters are now simply missing from the PDF file created). Personally, I hate java so it would be great if it was written in a laguage that does not require additional softwares, but it's only my problem (?) and does not effect productivity. Keep up good work, Neo!
