Expose views settings & arguments

I agree, I did not know that page existed and this module makes that redundant. Those docs would mean making a custom element per View, instead of this module which makes one element where you select the View.

One area of trouble implementing multiple custom arguments is that there is no field type in Site Studio that can accept an array. So if you wanted to pass mulitple terms, in this case, I don't think you can. The form tokens in Site Studio are not like regular Drupal tokens nor is there a way to 'process' the input and concatenate it (+ or ,) for Views.
