This document discusses the research on developer interactions within integrated development environments (IDEs) conducted by Roberto Minelli and collaborators. It breaks down how developers spend their time in various activities such as editing and navigation based on recorded interaction data. The findings point to ways to enhance development environments by understanding current usage patterns.
