Added second button

Added second button + a demo in the sample app.

Second button can be added with Builder. Has similar methods as the 'Endbutton' methods.

Like the idea but there are a few things I'd like to see changed :) just trying to make the code as great together as we can!

• Removing the methods which add listeners together, as I don't think they are useful enough (I like the API to be as small as possible)
• Not having a second button by default but if someone wants one they have to add it themselves using addSecondButton() on the builder

If you'd like me to, I could create a PR with what I'm thinking?

Then we can compare the two

Sure! I agree with your remarks. I dont really know what you mean with inconsistent format ( Im not at all a professional software designer).
