VS Code 1.129 introduces an experimental unified editor panel within the agent’s window, allowing users to review and interact with agent-generated changes using a familiar tabbed interface and standard editor features. This integration streamlines workflows by enabling seamless file browsing, diff viewing, and in-editor testing without leaving VS Code, enhancing productivity and user experience.
VS Code 1.129 introduces a redesigned editor panel within the agent’s window, enhancing the experience of reviewing an agent’s work by making it feel like the standard editor interface. Users can access the agent’s window via a button at the top, which opens the prompt window to start or continue sessions. The interface displays the conversation with the agent alongside a detail area showing files and changes, a layout familiar to existing users.
The key update in version 1.129 is the unification of the editor in the detail area into a single docked pane with a shared tab bar. This change eliminates the need to switch between separate panels, allowing users to review changes using the same tabs, diffs, and keyboard shortcuts as the main editor. This feature is currently experimental and requires opting in through the settings by enabling the “single pane detail panel” option and reloading the window.
The video demonstrates using this new layout on a project involving color themes, where the user adds a new “sunset” theme. By starting a new session and providing the necessary files and permissions, the agent processes the request, and the changed files appear in the unified tabbed editor. Users can easily view diffs, browse the entire file system, and open multiple tabs to compare files side by side, streamlining the review process.
Additionally, the integrated browser within the agent’s window allows users to test and iterate on the agent’s output without leaving VS Code. This seamless workflow means users can quickly make adjustments and verify results, such as fixing a non-working icon, all within the same interface. This integration reduces context switching and improves productivity when working with agents.
Overall, the new editor panel in the agent’s window makes reviewing and interacting with an agent’s work feel natural and efficient inside VS Code. By consolidating tools and views into a familiar editor-like environment, version 1.129 enhances the user experience and supports smoother development workflows. The video concludes by encouraging viewers to try out the feature and enjoy coding with the improved interface.
