Comments on Adobe AIR:
The popularity of AIR is somehow questionable. However there are some very useful applications out there. If you don't want to install AIR on your computer, you can use the online version.

On OSX, Linux, UNIX you can only load/export/save from/to the application storage directory.
OSX: /Users/USERNAME/Library/Preferences/APP_NAME
Linux (ubuntu): /home/USERNAME/.appdata/APP_NAME

For issues, please use the google code issue tracker (requires a google account)
If you have any ideas drop me a line

The application uses a custom, minimal ui framework (src/neolit123/ui)
you can use it in your own project if licenses are compatible.

The module editor is based on the ScriptArea component by Victor Dramba http://www.victordramba.com
