It would be really great if this module could somehow integrate a progress bar for uploads, to show what percentage of the upload has been completed. Sometimes when uploading particularly large files, it can take up to an hour, and my clients are never sure whether it is working or not.

I'm not sure how exactly you would do it however, seeing as the file attachment is done through a page load. The only real way I can think of is through an AJAX upload, maybe implementing the Upload Element module.

Regardless, thank you for your hard work in maintaining this module. I have used it on many sites, and will use it on more in the future.
