It looks like this works well from mobile until you try to edit and the keyboard covers the code.

Sliding the animation off screen to make room if a soft keyboard is detected might allow this to be used on phones.

Sorry for not having any instructions- just hold right on the edge of the code and slider- and drag.

You can resize it. I know it's not ideal. Did not realize this would get used widely.
