Playlist CSS to display thumbnails on right of video

Providing custom CSS is beyond the support that I as the plugin author can provide.

Here is some css that may get you closer.

.flowplayer {
   background-color: #ccc;
   /* allow room for playlist buttons */
   margin-bottom: 100px;
}

.flowplayer .fp-playlist {
   position: absolute;
   bottom: -100px;
   width: 100%;
   text-align: center;
}

.flowplayer .fp-playlist a {
   display: inline-block;
   width: 70px;
   height: 70px;
   border-radius: 70px;
   background-color: #666;
   margin: 15px;
}

.flowplayer .fp-playlist a.is-active {
   background-color: #eee;
}

.flowplayer.is-paused .fp-playlist a.is-active {
   background-color: #ccc;
}
