I noticed the change in the flag area [upper right on entry] and just want to thank you for all the effort you went too ot implement it. I am assuming that the 'unread' tag refers to me only.
As a retired programmer, I have spent a few mind cycles trying to figure out the implementation details. I appreciate the amount of design and coding effort that went to this feature. I know it was not trivial.
Again, thanks for the effort.
