Progress bar for file uploads

Description of the limitation and why it is relevant to address

It would be nice to show the user the progress of file uploads, especially when uploading large files (hundreds of MBs). In this way, the user knows for sure that progress is being made.

Submitter proposed design (optional)

The current file upload window already shows some feedback to the user “queue, uploading, processing”; simply adding the progress as a percentage to these messages should be sufficient.
