Changing the layout of subjects
Adding the old subjects back in with a new style. I have also added a progress bar at the bottom so you can keep track of your progess through a subject. I also have added a feature for swipping left to turn over the page. Which I think makes the subjects feel a little more enaging, finally I have added a feature for which you can save a formula in the formula section for quick access later on. You can do this by tapping the plus symbol on the right-hand side.
