Just a suggestion for devs: add an icon to the left of each item in the Sources list representing its type e.g. audio, video, text or still image, to make it easier to quickly scan messy source lists.
To conserve real estate, consider replacing the eyeball icon with these icons and adding a strikethrough to represent a hidden source.
