* Catalog (aka Store) is very slow and clunky. Takes 5-10 seconds to flag episodes as "Downloaded" after I click on a podcast I have episodes for.
* Clicking download button takes 4-5 seconds to react. Progress of download is not shown in store, but only in Library.
* No connection between podcasts you downloaded and those in the store. So if you want to get more episodes, you need to search again. Why?
* No way to add podcasts by URL.
* Descriptions are cut-off after a line or so with [...], even if you press the "i" button.
* No position indicator. Oh wait, it's hidden behind the cover image and you need to tap to switch. And that's the default view every time.
* The position indicator has buttons at either end. They don't do anything. Or do they?? They're certainly really small.
* Some of the stuff hidden behind the cover image is a button. Some of it is just shiny bits of the reel-to-reel. Guess which is which from a foot away!
* Only fast speed is 2x which is too fast. Only slow speed is 1/2x which is too slow.
* The share buttons everywhere just link to the podcast in general, not the episode.
* Generally sluggish on an iPhone 4.
Honestly, this seems like the kind of stuff Apple is supposed to be better than.
