I just made a change in NetNewsWire that will appear in the next beta: if you drag a URL onto the Subscriptions pane, then that annoying dialog that used to appear doesn’t appear anymore. It just does it, it just subscribes to that URL.
This makes it easier to subscribe to sites you find on the Web. For instance (at least with Safari and Camino), you can actually drag-and-drop the orange XML buttons onto the Subscriptions pane.
Until the next beta appears, you’ll still get an annoying dialog box, but that will change.
P.S. Lots of people have asked that you be able to drag-and-drop a URL onto the Dock icon. I wish I could do that. Unfortunately, the Dock has no facility for accepting drops that aren’t files. So I can’t make that feature happen. Maybe in the future some day.
