+| `--list` | List all resources in the save, grouped by type (capped, crafted, special, locked) |
 | `--max-resources` | Set all capped resources (`max > 0`) to their max |
 | `--set-crafted=N` | Set all unlimited/crafted resources (`max == -1`) to N |
+| `--only=a,b,c` | Only affect listed resources (comma-separated, case-insensitive). Matches resource names (e.g. `Food`) or internal keys (e.g. `food`). Applies to `--max-resources` and `--set-crafted`. |
 | `--no-copy` | Print the edited save to stdout instead of clipboard |
 | `--help` | Show help |
