I'm really loving Ginko right now! It feels really smooth to control and it's doing everything I need it to. As an avid Vim user, I really appreciate the use of homerow keys as movement controls. I would just like to suggest that you add the Vim controls for adding a new line (in this case a card) with "o" for new card below and "O" (shift-o) for card above. I keep pressing o out of habit, and I'd love it if that functionality was implemented!
