Learn about various horizontals such as localization, globalization, security, analytics, user feedback, device management, and accessibility. Understand how these elements, often referred to as "paying taxes," are crucial across multiple projects despite not introducing new features. Gain valuable insights into how the relevance of individual horizontals can vary depending on your target market. Delve into the importance of balancing feature development with these necessary non-functional aspects of software creation.
