Notepad screen shot
This screen shot of NetNewsWire Pro’s Notepad should be fairly self-explanatory.
As an homage to Frontier, the keyboard shortcut for opening the notepad is Cmd-Y.
It’s not a document-based outliner—there’s just one outliner window, and its file is stored on disk in one’s Application Support/NetNewsWire/ folder. It gets saved automatically when you make a change.
Perhaps unsurprisingly, it’s an OPML file.
And yes, one can expect the toolbar icons and other cosmetic issues to improve between now and the first beta.
