Cool app in a lot of ways, but its conceptual hierarchy seems weird to me so far — the main section that you're presented with upon launch (the "Library") has a tab bar at the bottom split between "Podcasts", showing podcasts you've subscribed to and/or downloaded episodes from, and "Top Stations", showing popular podcasts on the iTunes Store. So far so good. But then there's also a "Catalog" button at the top-left that "flips the app over" (a la iBooks) and shows you a general store-browsing interface. The corresponding button to get back—which, I'll note, is on the opposite side in that view!—is labeled "Library". tl;dr: There are Store interfaces in both the Library and the Catalog, seeming to break the conceptual hierarchy, and thus annoying me.
