This is ONE OF 2 responses to volume 2, Robert Card Number 6 ("Suggeston Response")...
As a follow-on to Robert's suggestion on distinguishing seen & unseen messages:
The next logical step is to provide a summary statistic of messages unseen on the index screen (e.g., 75 cards, 23 unread). I spend many hours every week on a similar system for work and this feature is VERY useful as a time-estimator.
[Editor's note: an excellent idea; consider it done!]
Kudos to John for this issue's improvements. Archipelago is *vastly* improved already.
