Show only downloaded items
Use cases
Before going to a place where I knew I would have no access to the internet, I downloaded a bunch of podcasts. Later (no network available), I could not find easily the shows I would actually be able to listen to.
Actual behavior
The whole list of podcasts (both available for download, and already downloaded) is shown.
Desired behavior
Only the already downloaded stuff is shown, or there is a way to filter out the noise.
Benefits of the solution
Whether networking is enabled or not, the app only shows to the user useful stuff she will actually be able to play.
Possible drawbacks
The app should be notified of the availability of the connectivity in order to show or hide episodes available for download.
