Decent
Powerful, but there is 1 bug and a UI/UX opportunity. When the display is full, adding new characters does not scroll visually, but logically it did. Thus, one need to move to the left to refresh, even though the new characters are on the right. This is known as happened on Mac but fixed already. Overall, the UI could be improved by allowing gestures instead of relying solely on the arrows, and adding landscape support with the additional buttons.
