We've seeen lots of users that are confused with file uploading. They don't understand that an uploaded file that is shown in thelist of files has to be confirm by 'save changes' button.
I tried to change the page to make it easier to understand.
Whats changed?
An additional text line gives advice to confirm upload.
Button 'Save changes' is directly below the text information and 'Cancel' button is moved to the right.
