More shortcode settings?

Are there more shortcode settings besides these?
[Youtube_Channel_Gallery feed="user" user="myuserid" feedorder="desc" videowidth="500" ratio="16x9" theme="light" color="white" quality="small" autoplay="1" rel="1" showinfo="1" maxitems="9" thumbwidth="90" thumbratio="16x9" thumbcolumns="3" title="1" description="1" thumbnail_alignment="left" descriptionwordsnumber="10" link_window="0"]

Its not showing a link to show more videos, just the 9 items.

And is there a way I can move the text below the thumbnails without editing the plugin?
