NetNewsWire 2.1 is out, and works much better. I hadn’t read the changenotes yesterday, but today I found this inside:

The splitview is now one-pixel wide, like the kids like so much these days. There?’s a little grabber thing below the subscriptions list too. (Using RBSplitView, which rocks: /src/rbs.html)

Thanks for the kind words Brent! Hm, I really must find some time to update the page with recent users of RBSplitView… I think about a dozen or so…
