There are two things that seem missing when creating React visualization plugins.
- Passing editor config values to your React components that don't get saved in the plugin saved object. (i.e. editorConfig: {collections} is not possible since these are not passed in as properties to the React components).
- Getting access to the config object to load objects from the ui_setting_default.js file. I feel like this should have been in the vis.API object but it's missing.
