Hi! I think it would be great if we could add the possibility to create custom components for nodes in Cocos Studio. Since it seems already possible to define custom nodes with properties I guess it should be doable. (http://www.cocos.com/docs/document_en/index?type=cocostudio&url=/doc/cocos-docs-master//manual/studio/v4/chapter3/Extend/Directory/../WidgetExtend/en.md)
What do you think ? Are there any plans to implement that already ?
