Add something like "+" indicator button, to expand the media source section
[EPIC] Extend Media Management Area, improve UI... (aura#390 - closed)
Parent:This enables users to add additional media sources. This should replace the current "[ ] expert mode" checkbox.
The button to expand for additional media sources can be relativity subtle, since this is not a high-demand feature. The regular use case is a single media source per episode. That's why we previously settled for "expert mode" and we wanted to somewhat hide it.
