I just noticed also that KMail’s next/previous message keys are Right/Left Arrow, whilst Up/Down Arrows ALWAYS scroll the message. THIS MAKES TONS OF SENSE!!! I always hated in Evolution how if you hit the Up arrow while the message list is focused, you go to the previous message. In other words, you either had the message pane selected and up/down moved between messages, or you had the message preview pane selected and up/down scrolled the message. This makes kmail tons more user-friendly, IMO!! Nice thinking, kmail guys!! Also, the fact that you can configure your keyboard shortcuts in KMail (in ANY KDE application) is WAY more user-friendly than Gnome’s model which doesn’t let you do this without becoming root, searching through XML files, etc., and editting the XML files by hand to change the keyboard shortcuts. KDE even allows you to have more than one shortcut assigned to a given action. See, little things like this have always made KDE more user-friendly to me.
Awesome job, KDE guys!! =:)
