Add an option to change when the thumbnail is overriden
On my old phone the podcast artwork would only change to the custom one when it was set as watched or yet to be downloaded.
I really liked this bug as it both easily showed what I haven't yet seen and was generally a nice adition to the feel of the application.
It would be nice for it to be an option for deciding when the thumbnail switches to the custom one, that way it is open to customisation and doesn't effect anyones experience negatively by changing up how the customisations are presented to eveyone.
Tjank you for your time :)
