Works for me.

My remarks:

1) No debian packaging yet => no way to integrate it to extras yet. Don't forget about optification when doing debian packaging, pls.
2) You can create project page at garage.maemo.org if you wish
3) The folders are shown as a list, not as a tree. Hierarchy is lost from end-user PoV
4) Would be better to have the nice launch icon in Applications. This way, the application will be available not only for geeks but for wider audience.
5) [ Dream ] The perfect way is to implement this application as a control panel applet. Control panel applet is a so-file, loaded into the CP process in run-time, it can not be written directly in python. I am not a python programmer but I can imagine the schema like this: C-function calls python interpreter to build widgets inside C-application. Some kind of mix. I was doing this with Tcl/Tk several years ago. I believe it could be possible with python also.
