Sorry if this is the wrong place. While I enjoy using Barca 2.8, I have found one thing that is missing (or I am looking in the wrong place for it.)
1. There appears to be no Help entry for Folder | Folder Tools | Tag Duplicate messages.
This is a really useful option when I have had to create a new Google account and ended up with a bunch of duplicate messages.
2. I did find in the Help file "Special Identifiers," the Staus:r for read messages etc. A new trick since I was used to Barca 2.5 with option to display only read messages in a mailbox right in the Showme area.
But it took me some time to find the "Special Identifiers" information and I found it by accident.
