Make optional deleting from playlist by sliding sideways

[ghost]

Dear contributors, thank you so much for putting your time into making this very very nice app!!

Please consider making it optional that podcasts can be deleted by sliding them sideways in playlist view. I already deleted dozens of files by accident and re-downloading is tedious, when no fast internet connection is available. Thanks!

This just started bothering me recently. Good timing on this. :-)
