I found a thing that is not really nice... (Although MS does this in the 2003 Version)...
The Problem is: I use the Mailfilter to put the Messages in Subfolders. But now I cannot see that there is a new Message in this Folder if it is not expanded!!
I think this option should be added in preferences - I think Squirrelmail calls this "Kumulative Announcement" (or something like that)
Is there anything planned for this?
