I've used netscape composer, amaya, emacs (which is more of an html code editor), I'm looking for wysiwyg (word processor type).
Now I think soffice's StarWriter is the best around. It acts just like a word processor, it has footnotes, doublespace, etc. It also uses good html. I checked my docs in lynx and they were quite viewable, and the double spacing etc looked great. I'm interested in this because my goal is to write all documents in an open file type that can be easily indexed and searchable in htdig. That way I can have a permanent and growing personal (searchable) library (one that would also be searchable over the network). I know there are lots of great word processors, but .wpd, .doc, .dvi, etc. are not acceptable. I hear gnome will have an xml word processor, that is something to look forward to. StarWriter is the best I've seen so far for Linux. The memory needs for this thing can be a bit too high for most users though. I can't wait to check out what the gnome word processor will do.
