I keep reading warnings that setting "Episodes to Keep" to All Unplayed will also delete podcasts from iTunes when you sync. As many of my podcasts are only available for one week from source this is not what is wanted. How, then, do I continue to do what I did before 'upgrading' to iOS7 - keep a full library archive on iTunes and only have unplayed episodes on the touch? Or have I misread and it is safe to change the setting to All Unplayed?
(I assume the subscription on the Podcasts app should be left off where I am using iTunes on computer to download new content.)
