Happiness for laypeople

I'm right now working on [an application](https://sunyatazero.github.io/buddhist-well-being-pyqt5/) for increasing happiness in everyday life, inspired by practical teachings in Buddhism about happiness for laypeople. My question is: What did the Buddha say about happiness for laypeople? I have found these Sutras helpful: * [Sigalovada Sutta](https://en.wikipedia.org/wiki/Sigalovada_Sutta) * [Dighajanu Sutta](https://en.wikipedia.org/wiki/Dighajanu_Sutta) What else did the Buddha say about happiness for laypeople?. (Is there a compilation of teachings regarding this?) Grateful for help and with kind regards, Tord
