We have a new feature in Hannover called "View Recent Collaborations." Samantha can right-click on any name field and pick a menu item to view recent collaborations with said person.
Samantha then gets a dialog box that lists her recent mails and chats:
We're at the stage of defining "Recent." Currently, it's set in Notes.ini with a default of 2 weeks.
I'm thinking that's enough at least for now-- Admins can change that default before deploying, but I'm hesitant to provide a user preference so that Samantha can set it for 4 weeks and Betty sets it for 1 week... while that might be nice eventually, in terms of getting users used to the feature
(e.g. why does this mail message show up in Samantha's but not Betty's?) and help desk calls, that the ini setting might be enough. We're still figuring out a way to let Samantha know what "Recent" has been defined as (short of telling her to read her ini file.)
