Submit button is useless in upload

When we upload a photo, what use is the submit button? If you leave the page without clicking, the picture is still in the album ... (even if in this case it does not appear on the outline)

This is the same behaviour as in 7.1.x and I have mentioned it before to those with similar questions  What the submit button does in this case is to submit the title, description, category, etc so that it is saved for the photo.  The photo has already been uploaded to the album.  If one leaves the page without submitting the information for the photo, then that information is not saved.

Yes that's right, I had never noticed this in 7.1. Can we take advantage of this new version to change this way of working?

How would you like it to be?  I guess there could be one submit button, the user would first fill out all the info for the multiple uploads and then hit a single submit button that would start the uploads and send the info from the fields.  However, with starting the uploads in the background; then a large upload could be uploading while the user fills in the fields.

I think I like the current way, the uploads uploading in the background while I fill out the fields.
