I love this plugin! One small issue though:
I haven't touched any settings apart from inputting my Youtube ID, and there seems to be a
style="width:4px; that is added to the div containing the thumbnails. I found this using Firebug. This 4px width is restricting the thumbnails to show in one column.
I searched for the file that might be adding this, but can't find any. Any ideas for a fix?
