To allow projects to be exported out and shared with other developers. And of course, it must be able to be imported back into AppGyver Composer Pro too.
This would allow developers to share their work with developers, and encourage the use of AppGyver in mobile app development.
Or maybe, a developer can work on a project and later send clients an export package for clients to build the app themselves.
I think adding this feature will allow so many use cases among developers.
