Quick note that version 1.1 has shipped and it adds quite a few new features you can include in applications built for Maemo with Illumination:

- A real "Do While Loop" block for proper looping.
- Full support for reading and writing text files (along with a multi-line TextField).
- The ability to run shell scripts (good for putting an automated UI on top of scripts).

And a bunch of other goodies.
