Add configuration options for sorting

**Problem**
When working with controllers, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or entry points. Start by locating the controller sorting and configuration handling, then clarify whether the goal is configurable sorting, more descriptive controller errors, or both. Done should include an agreed option set, defined error wording, and tests covering the requested behavior.
