[Plugin: WPaudio] Changing the width of the WPaudion scrollbar

I recently installed the WPaudio plugin and I really like it. However, I could not figure out how to get it to change the width of the scrollbar. As far as I can tell, the width of the scrollbar (and entire WPaudio section on the page) is determined by the length/width of the track name.

It would be very nice if there is a “width” argument to the [wpaudio] tag that could be used to set custom widths for the plugin.

Thank you
