Thanks your suggestion. That's pretty much what the library is doing. One thing the library does is if on their first visit a user has utm codes in their URL (e.g. utm_medium) it'll store this and make it available via pursor.convert() & pursor.fetch(). Currently the library looks for 'utm_source', 'utm_medium', 'utm_name', 'utm_term', 'utm_campaign', and 'utm_content' in URL. If I understand correctly you would like additional data collected by analytics.js made accessible via the library? I created an issue for your idea here (https://github.com/bilbof/purser/issues/1 https://github.com/bilbof/purser/issues/1).
