Drag and drop items using the library

[subbusgithub]

This is more of a feature request that an issue. I just tried this library and have to say, its really well made and easy to use. The only draw back I noticed is the inability to drag and drop items into a drop zone and the inability to select an object and move it using the arrow keys on the keyboard. Is that possible as of now? Because that is a feature I was looking for.
