It works ok but it would be great if it does not open new player every time you open new video. Please make it optional. Also adding to playlist does not work correctly. It opens new player instead of adding to currently open player.

I don't know if you read it but..

"open new player every time" - it depends on Player's settings:

"It opens new player instead of adding to currently open player" - also. See the screenshot
