My favour is the following order, sorted by priority.

1. Sub module
2. Super module
3. Current crate
4. Workspace crates
5. std/alloc/core items
6. External crates

However, the current auto-import feature enforces a built-in order which I cannot adjust.

It would be better if I don't have to reorder imports manually.
