Is your feature request related to a problem? Please describe.

It is common to use URLs of files stored in S3 buckets instead of data-URLs directly. Therefore, in addition to supporting data-URLs in the FileWidget, adding support for URLs would be highly beneficial.

Could you replace your FileWidget with a TextWidget using the Custom Widgets functionality? Or maybe you could build your own custom widget that wraps both, and let you pick which is shown?
