Often 2 things happen;

1) click extract, nothing happens. A loader and failover would help know if I am just in a waiting period or if it has failed.

2) Often after pasting a URL, another (perhaps default video) preview appears, not the video link I pasted...which I also have to put cursor at end of pasted URL and hit ENTER

@Krzysztof Szularz also curious, is this Open Source or shared anywhere? I want to embed something like this into a Goland program. Could help push it along possibly.

Thanks!
