EDIT: This is perfect! Thanks a lot! There aren't any touchpad gestures but the keyboard shortcuts would do for now :D
- Swipe left to focus the column on the right, swipe right to focus the column on the left (reading it, it seems counter-intuitive but doing it is almost perfect).
- Swipe up and down to slurp in/out.
