Update config documentation

**Description**
Currently config lacks proper sorting support.

**Proposed solution**
Add configurable sorting with sensible defaults.

**Priority**: Low/Medium

The issue names no files, tests, or entry points. First locate the current configuration documentation and the code that handles sorting, then clarify whether the expected change is documentation only or a new configurable behavior; done should include defined sorting options and sensible defaults.
