I thought that Liquid program looked good as well but not being a full blown writer myself I figured I wouldn't waste my 30 day trial but if it keeps going until you leave it alone for 30 days that's another story.

I did look in the Open Source world for anything that might help a writer organize his data and from my uneducated perspective thought yWriter5 looked good.

I figured it might at least help me to organize my gaming campaigns so I downloaded it. It was created by an author who is also a software developer so it could be good. There was also a published author who uses yWriter5 and she describes how she uses it in a little video.
