When you press on a user-sphere ( suggested People bar ), the mailfilter is set to show that person's mail.
But when i want to show the mail of 2 users in order to show some extra information????
I want to have the ability to show multiple users' mail !
Example: by pressing <CTRL> and users, it would be great to show the mail for THAT set of users.
This is an interesting idea. I'm not sure -- compared to some of the more pressing requirements -- this one will be a high priority.
