For those interested in enhancements to the Design Studio SDK, I have recently submitted the following ideas in the Idea Place:
Provide SDK Support for the callRuntimeHandler function with Handler Type "sapui5"
Provide SDK Support for the UI5 sap.m (mobile) Library
SDK Component Handler Type for Technical Components
SDK access to list of all components in the application
Remove 10,000 cell result set limit for SDK Components
Allow Script API Calls from the Additional Properties Sheet of an SDK Component
