Atom has introduced a new feature in its 1.37 beta version that enhances the pull request review process by allowing users to view and respond to review comments directly within the editor. This feature includes a dock next to the editor that displays comments, provides navigation between comments and code, and enables users to resolve comment threads, which advances a progress bar reflecting unresolved issues. Additional functionalities include showing diff formatting, expanding and collapsing comment threads, and navigating changes with line highlighting and gutter icons. Users need to be signed into GitHub for Atom to access certain features, like highlighting and icons, and can update their work by checking out different branches or refreshing comments. The design, aimed at creating an editing-centric experience, was developed based on user feedback, emphasizing the importance of an intuitive response flow and the use of emojis for expressing feedback. The feature also includes safety measures to hide potentially abusive comments. Users can access these enhancements by downloading the beta version and are encouraged to provide feedback through the Atom repository.
