After upgrading to the new version I really miss two features that was a big part of why I decided to buy Touchdown for iPhone.
1. The setting "Don't mark read on server". This setting allowed me to mark emails as read on the phone without marking them as read in Oulook and on other devices which I found extremely useful
2. The option to show all unread messages in Touchdown without having to search for the subfolders where the unread emails are. (I understand that I'm not the only one who used this feature!)
I would very much appreciate if these features were restored!
