I hadn't thought about the use of randomization in the carousel. I'll need to put some thought into adding that in the next update.
In the meantime, I think we can hack this in for the simple case. I would start by creating a predefined list where each item is the name of a question involved in the carousel. Then we can create a constructed list that randomizes that list. Finally, we can update line 6 of the carousel footer to set the pages to our randomized list:
var pages = [% ListLabelsArray(list1) %];
"list1" being the name of the constructed list.
