Future:

• Tests
• Redo styling - currently utilizes a massive stylesheet, want to move to emotion or something else
  • this would require Kizen to export its styleguide or make it consumable
• Cleanup a lot of the unused code - idea is this library should be good for now but we should aim to improve it every time its touched
• Better mobile responsive design
• Move this to a github package? - free and private!
