Not to be deterred, I now have this program working in Windows. It is for novel writing, not academic writing, I can tell fairly well. What do you use it for? Shedding Khawatir uses it for all research but I am not yet sure how.
What do you use beyond a word processor, file folders and index cards? I file things on secret blogs, which can have Pages and Links that allow you to see where the other pieces of the text are at all times.
What about Zotero? What about JabRef? Is EndNote necessary?
