This is purely a concept and I have no idea how to to create it but I would really want it on my pc. By unity clipboard, I mean an interface, like the unity launcher but on the right side of the desktop, that could be used as a temporary holder for whatever we want to copy or move. You get that? You just drag a picture to the clipboard from a folder to pin it there and take it again to use it in a document; Not only files but also texts and also direct download from the webpages. It would be really easy to move files.
Again I say it, this is purely a concept and I have no idea on how to do it. So if anyone have any idea how to do it or something near to it, please say.
