The Web Outliner for OPML?
A couple of years ago, someone e-mailed me saying that they had taken my JavaScript Outliner (sample) and built a bunch of additional features into it. I would really like to try doing more of my outlining in a web browser now, and I like the Radio UI. However, I can no longer find the pointers to this application. If anyone reading this knows where the tool is, please post in my comments section.
