Don't delete podcasts on holding 'next' button.
Problem with this is that in the current interface, it is much too easy to accidentally trigger. In full-screen the 'next' button is massive, and I had multiple times that I (apparently) still had the phone unlocked, but grabbed the touchscreen and deleted the podcast.

You can uncheck this option already.
Settings-> player-> player controls
then all the way at the bottom
