 - A widget for the home screen and lock screen: the unread count, and the episode you were on with a button to resume or pause it (#428).
 - The icon's count stays right with the app closed: ipx sends it to the phone when it changes, once its `[push]` is set up, in place of waiting for iOS's background refresh (#433).
 - Presses are felt: a light tap on play, pause, flag and pull to refresh, a success on marking read, a warning with an error (#430).

+- A question the page asks before going ahead (deleting a file, sharing an address that carries your access) is shown with Cancel and OK, rather than answered Cancel at once with nothing shown (#453).
