[Plugin: ProPlayer] Making the playlist smaller in height?

Hi, I was wondering if there is a way to make the playlist below the video player smaller in height. Right now it shows 1 and a half videos and it doesn’t look good, I would like to reduce the height of the playlist so that only one video shows at a time. I tried to increase the height in the proplayer code on the page but that just makes the actual video player smaller, the playlist stays the same size.

Thanks in advance!
