Great idea! And +1 for the Github repo.
I haven't actually installed the plugin but I glanced at the code. I might be wrong but I think there might be a missing caveat. For example, suppose I have hundreds of questions in my site and I configure the question list to display 10 elements per page. I browse a page in which 8 out of those 10 questions are questions that will be hidden. Will the question list display 10 or 2 items?
