Beingmanan.com has spotted a new patent filled by Apple, which focuses on the interaction between the user and the file system via drag & drop.
According to this patent Apple is working on a “smart drag & drop” solution, which should enable us to sort documents into folders basing on the file types, rather than manually organize them. Pretty much like those folders actions that already let you automatically move a file into a specific folder, but built in in the OS.
To me, it sounds great. I expect this exact kind of things from 10.7, revamped and brand new user interactions.
