Hi Peter, i am loving this ability to touch the screen and stop the auto scroll and then trigger it on again, the only thing that could be better with it is using the switching area more wisely and making it easier to flip from one mode to the other while performing.
At the moment you have two buttons that hog up the space that do nothing when using synced lyrics and a very tiny space to enable and disable auto scroll, i would suggest whenever we use time coded lyrics these buttons dissapear and we get a nice LARGE BUTTON to hit labeled SCROLL MODE under the button and AUTO or MANUAL written iside the large button so we can clearly and easily see where and what to press , at the moment this space is poorely utilized.
