Developers often create productivity tools to reduce repetitive tasks and focus on more demanding work. These tools are born out of a dislike for mundane tasks, allowing developers to automate processes and spend more time creating useful applications. Examples include self-destructing messengers, package delivery automation, search engine integrations, and even an April Fool's joke in the form of a CSS API client. The desire to automate everything is common among developers, leading to innovative solutions that improve efficiency and productivity.
