Version: 1.9.6 (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.20-16-generic When reading an email in a message window, the user should be able to "mark the message as" like the main window allows. Also, the user should be able to filter classify the message as spam. The user should not be required to close the message and go to the main window in order to mark the message, IMHO.
You can add that buttons to the toolbar.
