Export data from application

It is big problem to export saved request to a file within an chrome application. HTML5 (either javascript) don't have any API to save any data in file (outside applications sandbox).
Normally with application backed it would generate this file on server side and pass it to browser as a file.
In Chrome environment  it is not possible. There is no backed and can't force browser to generate file.

Anyway, lately I've started writing application backend on Google App Engine. It will have ability to save form data and restore it on demand. It also will have ability to share this data.

It will be available in future release.
