We have a use case where users will upload large files (250mb+) and we want to give the user feedback that their file is uploading. Currently the S3 uploader button shows the loading state but its not clear enough the user that action is happening. Ideally we could show a modal with a loading bar, or at minimum hoisted loading state for the entire app while the file is being uploaded.
Hi @snommis We don't have a great solution for visually showing file upload progress 
But I'm wondering if you could switch to using an S3 query instead of the s3 component & then you can set the loading state based on s3Query.isFetching:
You could also have the app in a container where the loading state is based off of the s3 query
