| // - If your thing is only used in one place, just put it in a reasonable |

| // before after so many years of development, it's probably not going to be |
| // used in other places in the future unless you know of them now. |
| // |
| // - If your thing is used by multiple callers and is UI-related, it should |
| // probably be in app/win/ instead. Try to put it in the most specific file |
