This would be a fantastic tool to use. Thank you for working on this.
I tried using it but ran into some errors.
I tried the channel download feature and it will only work when selecting MP4. Also when I add a channel I simply get a spinning wheel inside the ADD button and no indication that the channel was added. The downloads folder does get populated with videos as it downloads them though.
I did not try the playlist feature.
The individual video feature does not work for me. When I change the GUI from Audio Only, the default, to Video and Audio the drop down for format does not change and I am unable to select MP4.
