A Unity editor extension that adds a SubclassSelector dropdown to the Inspector for fields serialized with Unity's [SerializeReference] attribute. It lets developers pick concrete types for polymorphic fields, with fuzzy search, collection and nested type support, and value-preserving type switching.

Use cases

• select a concrete type for a SerializeReference field in the Unity inspector
• serialize polymorphic interface fields in Unity
• switch the type of a managed reference field without losing data
• copy and paste managed reference values in the Unity inspector
• customize type display names in a SerializeReference dropdown
• support generic SerializeReference fields with covariance and contravariance

When to choose

• you use [SerializeReference] fields and need a friendly type picker in the Inspector
• you work with polymorphic data models in Unity 2021.3 LTS or later
• you want value-preserving type switching and copy/paste utilities for managed references

When to avoid

• your project targets Unity versions before 2021.3 LTS
• you only need plain serializable fields without polymorphism
• you need runtime (non-editor) serialization changes rather than Inspector tooling
