+* **Enhanced retrieval & refactoring capabilities**: The plugin supports additional tools (e.g. type

 * **Enhanced performance**: Faster tool execution thanks to optimized IDE integration

-* **Enhanced retrieval capabilities**: The plugin supports additional retrieval tools for type hierarchy information as well as fast and reliable documentation/type signature retrieval
