Thanks for putting out the beta version of the slideshow format. I have several customisations I wish to make but will ask one question at a time. :)
I would like to change the thumbnails below the Slideshow to be square like the way the visual index format does. I have looked through the .css file of the visual index to see if there are some parts I can 'borrow' to edit the Slideshow .css file but am unsure.
The page I am testing this out on is:
