I have 3 screens on my phone. A home screen and 1 screen to the left and one to the right. Is there a way to make multiple wallpapers and have them change when I swipe left or right from my home screen?

Yes, following example is for screen 1 but you can do the same for the others:

  • Add a SHAPE module to the root, set shape to "Rectangle"
  • Select the width option and turn it into a formula using the calculator icon on top, enter the formula $si(rwidth)$
  • Select the height option and turn it into a formula using the calculator icon on top, enter the formula $si(rheight)$
  • Now, go to the FX tab, select Gradient -> Bitmap and place your image
  • Finally go to the "Animations" tab, add one animation of type "Scroll", tune params so the rect will only stay on screen one and scroll away
