This means that while there are not many useful ready-made widgets bundled with Kivy, you can hack together anything you need in a few lines of highly readable Pythonic code.

The modular API design pays off nicely, thanks to its practically limitless flexibility. The end result meets your application's unique requirements perfectly. The customer...
