Improve controllers performance

**Description**
Currently types lacks proper filtering support.

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

**Priority**: Low/Medium

The issue names no files, tests, or concrete controller entry points. Start by locating the controller and type-filtering code, then determine the required configurable options and sensible defaults; done means filtering is configurable and controller performance improves without breaking existing behavior.
