The application is incredibly fast and I love it for that. I make a lot of lists and the only time I ever wish I could work faster is when I need to move things around, switching between selecting and writing. My suggestion is to give another option for the S Pen button, providing a toggle between the pen and selection tools (and optionaly the eraser when the finger eraser is disabled). It would be simpler and faster compared to the current option. A button onscreen or toolbar change would also work, I just want to be able to switch between them with one click.
