Auto-Delete Policy

I use DC all day, every day, generally very happy with the app. Using it on a Samsung Galaxy S6. I listen to a ton of podcasts, and usually have a big backlog of episodes in my playlist. I have the Auto-Delete Policy set to 'Done Episodes', since having to manually delete episodes is a lot of work, and the other options ('As space is needed' and 'Keep latest X') are somewhat vague. Can someone give me a rundown on how those options work? The 'space needed' option sounds like my phone hard drive would always be on the brink of full, which would present problems for taking photos, etc. The 'Keep latest' sounds ok, but there doesn't seem to be a way of setting the X and I can't tell if that's the latest X number of episodes per feed, or some total for all feeds, or something else.

The problem is that every so often (every few months), the app will crash. Not a big deal, the app is generally stable. However, the app will crash, but tries to play every episode in the queue while it's crashing. This marks all of my backlogged episodes as done, and deletes them. Usually there's a minute or two lag and I can retrieve a few episodes, but I usually lose a lot of episodes and have to re-download when I get home to Wifi. Accepting the fact that apps will crash, can we get a tweak to the Done Episodes option, so you can set it to not delete anything until it's been 'done' for an hour or a day, etc.?
