Offline mode [feature request]

[sorjgdojbodjhdo]

Hi,

I recently discovered the app and so far it's been great. However I would love to have a download option where I can listen to the downloading files offline directly from the app. I've looked everywhere and self host podcast managers are really difficult to find.

If I knew how to implement the feature myself I would try to do it myself but I don't.
I imagine something like a small download button for each podcasts and when accessing the app without internet having a small green dot or some indicator near the title to show that the file can be played without internet.

Thank you for your great work,
