Is this new on the iPhone?

I’ve been testing a new Google Reader app over the last few days called Reeder, and noticed a UI piece that I hadn’t seen before on the iPhone. Check these pics:

On the first one, check the small dot in the upper right. If you swipe it, it folds to the left and shows the text on the second pic. Swipe back, and it goes back to the standard connectivity/time message. This is the first time I’ve ever seen an app take over the title bar…some make it go away, but this is the first I’ve seen with this behavior.

Are there any others that do something similar? It says something about the tyranny of the Apple UI guidelines that this shocked me so much.
