After (repeated) bad experiences with Writing Outliner, I'm not trusting anything that developer produces, ever again.

He might be a "great guy" but ime he's an incompetent programmer. Having a Scrivener equivalent within Word is a great concept but having your work vanish? Not so great. Not just with one version, but EVERY version I tried. After #3, I finally got the message that the guy didn't actually know what he was doing.

Perhaps he's caught on to the whole programming thing since those early days, but I'm not about to find out.
