Add a toggle for download on wifi only to the download menu
Having a second copy of the download over wifi/data toggle in the "downloads" menu would make it much easier to find (since it's an infrequently used setting, most people won't know where it is, and when looking it makes sense to look in "downloads" for the option.

Currently from the download manager this is 3 taps - drop-down > network settings > episodes download. Steps 2 and 3 are both top of list. Might be better added to navigation sidebar than download manager
