Please check All-in-One Calendar app on appexchange that extends data visualization capability with drag&drop multilingual calendar, intuitive planner and GeoMap layout. App works in lightning, classic and SF1.
Similar question, is there a drag and drop for Contacts? Like if I upload a candidate's resume/cv to Lightning, is there a feature that will autopopulate the candidates contact info into the appropriate fields? (i.e. Name, Phone, Email, etc..)
