The viewer.js code does exactly what I need it to do and I would like to keep using it; however I am getting the following warning in the console that I have linked to the viewer.js code:
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/.
Is there a plan for updating the XMLHttpRequests used in the code to asynchronous to ensure the usability beyond when the synchronous requests are no longer supported?
