But everything is still clickable and swipable. The program still has as many features, but it's not visually complex: we don't show them to you. Want to commit your changes? Just click on the white space about three quarters of the way left to right, and two centimetres down from the top of the screen. About 50 pixels right of this, we have conveniently placed click listener that will revert all your changes. But don't worry, in the name of eliminating visual clutter, this click listener is entirely invisible.
