From my Evernote days, I miss one feature: Dragging a PDF (or a file in general) into the note list creates a new note with the file name as the title. The same with multiple files creates multiple new notes.
I know if I create a new note and drag on drop it into a new note, the file name gets filled as the title, but I always have to create a new note before I can drag the file and I can just drag one at a time if I want a note per file.
