In the new version, I really miss the ability to see email and organization as part of the Attendee List while a session is underway. It used to be off by default but you could turn it on and widen your pane or scroll. Plus, we used in the SEARCH field to randomly see how many people from XYZ were online. I think you could also right click on a name and see the email address.
Please bring these features back. Viewing the organization names can be more valuable than the attendee names in some cases.
Now you can only copy email to clipboard (but cannot see it on screen). Of course all the info is in the registration and attendee reports, but we find this useful DURING a session.
