I googled but couldn't find anything.
Specifically I would like to add a new drop down menu with shell scripts as menu items.
If adding a new drop down menu is not possible, how to add shell scripts in top menu, so that it executes on click.
Thanks!
I think what you would like to do would involve creating an Appindicator. This can be done in python or in C. An example can be found here: http://conjurecode.com/create-indicator-applet-for-ubuntu-unity-with-python/
In order to run a shell script, you would need to use the subprocess module in python. In order to start using the appindicator module in python you would need to install the package python-appindicator by running
sudo apt-get install python-appindicator
