Diff Viewer
Diff Viewer adds a page, reachable from every project and session’s menu, that shows a side-by-side diff of every file differing from origin/main — modified files, new files, and images — for any git repo in the working folder. Files are editable in place, so a review that spots a typo can fix it with Save rather than a round-trip through an agent.

A repo picker lists every git work tree under the folder, including repos nested inside subdirectories. Edits are written into the selected repo only, and a repo without an origin/main ref is reported as having no comparison base rather than shown as an empty diff.
Hooks
Hooks: http.request.before, http.request.authed. No MCP tools and no settings — the page is the whole feature.
