GA Notes is a cool Firefox extension which allows users to add data to the Google Analytics so that it appears in a table format on the top of each report. Any Ga user who has this Firefox extension in his browser can add, edit and delete notes. The beauty of this tool is that you can search the results and also export the notes as XML/CSV format.
The Developer of this cool plugin Justin Cutroni says that GA Notes Runs on the Google App Engine. No data will be stored on the user machine or on their servers but stored only on Google Servers. The Firefox extension which provides the flexibility of entering and displaying the data does a encryption of data prior to all the processing and data storage on Google App Engine.
