- File and folder preview reports as Markdown (with diff blocks)
- Clickable jump links to file/line/column from preview and reports
- Live diagnostics and Quick Fix actions in editors
- Recursive folder processing with progress and cancellation
- Optional change highlighting in open editors
- Localized UI (EN, DE, PL, CS, FR, ES, IT, RU, JA)
