Text size adjusting

Nice. But the 100%-state a bit troublesome. It could be confused as empty. Will the text size be absolute jumps or gradual? Increase the size based on how far apart your fingers move, or flick speed.

If so, showing the size of the A grow and shrink while tracking to the bar graph could work. The min and max sizes could be gray, while the current size is black.

Fun stuff for sure!
