GitHub Copilot app adds side-by-side diff, terminal and browser panels for reviewing agent code

GitHub's blog walks through how the Copilot app now lets you complete the AI coding review loop without leaving the app. When an agent changes your code, three built-in panels sit side by side: a diff panel highlighting additions and deletions where you accept, comment, or request changes; a terminal panel for running project commands manually or via configured scripts (e.g., launching a dev server); and a browser panel for previewing web apps. The goal is to collapse the editor/terminal/browser tab-hopping that reviewing agent-generated code usually requires, with the human keeping final say over every change.
