So YouTube decided to style some of the things a bit differently in their default style. Such as the box appearing when pressing Add to under a video. One thing that annoys me is that it is so freaking small. I decided to dig a bit and made some small changes using StyleBot.

This is the CSS I ended up using, it is quite simple, but allows you to see more of your lists.

div#shared-addto-menu {
    height: 400px;
}

div#shared-addto-menu .playlists ul {
    height: 300px;
}
