Drag-and-Drop Media Uploader – Many websites have allowed this for quite some time, it’s a great time saver. Dragging files from your desktop or a folder on your computer right into the browser is much faster than searching through folders to find things, especially if you are do not store your files in a neat and organised fashion.

Here you can see the what happens when Posts is hovered over.
