upload multiple items at once on ArcGIS Online

Idea created by olivierdev on Sep 24, 2013
    ArcGIS Online now support several file formats (pdf, xls, ppt, image file, etc...).
    When you need to upload and share these items on a n organization portal for a project, it's really frustrating to upload these item one by one (specially if you need to upload dozens of files).

    It would be great to be bale to upload (by a drag'n drop for instance) several files at once (like in SharePoint.)
