Version: (using Devel) OS: Linux Installed from: Compiled sources Kmail needs a simple way to show/hide the message structure for non-plain text messages when the option for "show messages structure only for non-plain text messages is set. The message structure view pane takes up way too much real estate even when squished. You need to access the pane for a quick attachment download, but then you should be able to hide it without going back into configure kmail/appearance/layout. This is especially true for laptops with limited vertical resolution limited to 800 or 900 pixels.
