Hi @Sal 
We just transferred our widget to the new configurator because it’s much more stylish and convenient. However, we haven’t released new features for the app.
At the moment, we are working on a multiple categories feature and we’ll do all our best to release it as soon as possible. We’ll keep you updated in this topic - Select multiple categories
As for the bulk upload, it’s not available at the moment. I am so sorry 
We have such a request in our Wishlist. Please vote for this feature to get a notification upon its release - Bulk / Batch Upload of Media Files in Portfolio and in general to all widgets - #5 by Helga
