Not seen any sort of restrictions for downloading videos yet which is good, but the only feedback I have is that the button should have some sort of indicator that a video is downloading, I thought I was doing something wrong and ended up downloading 5 of the same video because it is not clear that the download already started.

So I want to add a note that this extension keeps prompting me to "rate it" with a popup which is very annoying considering I have actually rated it!
