Frictionless Screencast
If a picture is worth a thousand words, what is a video worth? Here's a screencast demonstrating the new user interface, right on the heels of OmniGroup demonstrating their less-capable but prettier interface for OmniFocus. I think Frictionless is far more capable because you can have as many of the Action Browser panes open at once as you want. But I've been using Frictionless for a year now, while OmniFocus has been changing daily, so I have the advantage of experience in figuring out what GTD users really need. Plus you can download and play with Frictionless now if you like.
