Whe you have multiple screens, multiple apps and windows sometimes move files, attacching files to a doc or an email could be mess, you just get lost. Yoink resolved this problem to me, not matter where I’m working if I have a file or an image at hand that I need to use o move later, just drag it up to yoink (even emaill attachments or emails messages itself) and when I need it, just drag the file where it belongs.
