Revision diffs currently stack changed files on a single page. On large comparisons, file and changed-line caps can keep some changes out of the view, making it hard to review the full set.

• Show the selected file’s diff and let users switch files through the collapsible file tree or Previous and Next buttons. Keep the selected file highlighted and visible in the tree.
• Include every changed file that matches the path filter in navigation and review progress. Remove the revision view’s file-count and changed-line caps while retaining the diff engine’s file-size safeguards.
• Open the relevant file when following a code comment, a marked range, or a blame link. Confirm before switching files when there are unsaved edits.
