A couple of follow-up wishlist items for the Combined View in NetNewsWire:

• Option-clicking on one of the disclosure triangles should toggle all of the items in the current view open/closed (like the finder does with folders).
• When using the space bar to go to the next unread item, I’d like the next unread item to be at or near the top in the viewable area, not at the bottom. I don’t like reading at the bottom of the window, feels cramped to me.
• ‘Arrow’ing down should scroll in the current post before it jumps to the next post.

Again, I highly recommend trying out this view – Brent did a great job on it.
