I created a new version in your repo to facilitate collaboration: https://github.com/Phuket2/Pythonista/tree/master

One issue that I fixed in that version is that the code above has 'border_width, corner_radius, background_color' written twice where I believe you intended 'border_width', 'corner_radius', 'background_color'.
