Lyrics line background opacity

Could we have an option to control how solid we want the line background to appear to allow it to blend nicely if overlay over a video. One can adjust opacity of background to their need but the text should remain unchanged

This is already possible. There is an opacity bar to the right of the color bar in the Line Background dropdown menu. Drag the slider down on the opacity bar to make the line background more transparent.

Awesome, thank you. I managed to see it now
