Usability: Draft and requiring 'Save changes' in Site legacy files seems redundant/confusing

I went to upload a system file (an image to be used by a theme) to the legacy files area. I clicked add, went through the upgrade, and saw the image listed on the list of legacy files and thought I was done. I did not realize that it saved it into a draft mode and that when I left the page my work evaporated. I'm not sure what the purpose/benefit of this draft mode is but it seems that requiring the user to hit save changes without much of a visual warning that they are in draft mode is going to cause some confusion. Usually when you upload a file and see it listed as an attachment then you are finished so this seems like strange behavior compared to the rest of Moodle file attachments. Peace - Anthony
