Version: kmail (using KDE KDE 3.1.4) Installed from: SuSE RPMs I usually don't use the preview windows because it is in my opinion to small. So I always open the mail itself with a maximized window. What is missing now are the navigation buttons for previous, next mail, reply, forward. I always have to switch to the kmail window to do one of this commands.
At least Reply and Forward is already possible in KDE 3.2 Beta 2. The rest will follow.
The navigation buttons: previous, next message are still missing in KDE 3.4.3. The same situation is true for other buttons mentioned in this bug. I hope someone will add also: "Previous unread, next unread".
