If you ever wanted to add a business data to Google Analytics to help keep track of marketing activities, industry news and GA configuration changes; you know how hard it is, in absence of built-in functionality. But GA Notes for Firefox lets you add business data to a profile, that appear in a concealable table at the top of every report. Any GA user who views a profile, and has the Firefox extension, will see the notes entered for the profile. You can add notes, edit notes and delete notes. Notes can also be exported in XML format for archival purposes.
