-  - "Implement click-to-expand row details with comprehensive download info"
-  - "Add toggleable global stats bar showing total speeds, ratios, queue counts, and queue size (disk usage not available from integration API)"
-  - "Use every relevant DataTable prop from the mantine-datatable docs"
-  - "Typecheck passes with pnpm turbo typecheck --filter=@homarr/widgets"
-  - "No regressions in existing functionality (context menu, sorting, filtering still work)"
