Launcher - dropping a file on a launcher should copy, move, open or attach that file in the app, mail, or folder

If a user drags and drops a file on top of a Launcher app, mail app or folder icon, the app should open the file, the file must be attached in the mail-app (Evolution/Thunderbrd), the file must be copied/moved to the folder or USB Flash Drive.

if two or more folders are open, maximize them and allowing drag and drop the file to the desired window.

Thanks in advance.

P.S.
I know it looks like other bugs, but I do not know if they cover all the aspects to which I refer.
