I forgot to mention I very much like this tool! Thanks for that.

A few remarks about the update.sh:
When I run it form the command line you wil notice the "/etc/init.d/hildon-desktop stop" and "/etc/init.d/hildon-desktop start" will give error messages and probably do nothing now. I does not seem a problem though as the menus on screen are updates when the new hildon.menu is installed.

What is the function of the "ping localhost " calls in update.sh
If you just want to wait some time you can use the 'sleep' command...
But why the wait for 10 seconds when all the work is actually already done?
