Elementary needs more robust drag and drop

I installed Elementary on a USB thumb drive and tried it out. I was unable to create folders on the desktop or drag and drop to the desktop. I didn't test it beyond that, but that was all I needed to see.

I have avoided GNOME desktop environment because it doesn't allow drag and drop to the desktop, to inserted sd cards/thumb drives, to the trash can, etc....

I continue to use Unity until I find something better.
