I don't know, I don't even feel like trying it.
I think on Reddit, it was said not to work properly.
This is the first report I have seen in the SF forum, though.
As it reads to me, it should pause after every X amount of downloaded videos, pause for X amount of minutes.
How they time that or accomplish that is unknown to any user, only to the developer.
It sure would be handy, probably for Amazon, if it worked properly and reliably. But I just don't download at all from Amazon with SF now.
