The Radio OUTLINER is a cool tool, which lets you organize your lists in an OPML file. Short, to the point, and subscribable, this is great for collaboration.

I know it is still a beta, but I'd like to see the ability to put the cursor mid line, and "break" the line by pressing enter. This does not work now.

What I like about it is the ability to subscribe to it. Radio users can subscribe to mine by clicking on the OPML coffee icon on the home page of this weblog. Once you subscribe, view its contents by right-clicking on the RU tray icon, choosing "open radio", and then going to Radio, Outliner.

Enjoy!
