Automatically export typescript files when newly creating an index.ts file.
While in an index.ts file, run this extension ("Export Typescript: Write exports") to add export * from ./<FILE_OR_FOLDER> for each sibling file/folder in the current directory.
Explicitly export declarations like export { Foo, Bar } from ./<FILE> by setting exportStar=false in the config.
Config
The default configuration exports all sibling .ts files and folders with a index.ts file.
