I also wish for multi-monitor displays, but in the meantime you can at least run it full-screen on one monitor and leave your second monitor free to do other things - browse the internet. To make this work, you need to set a launch option of -nopopupwindow and disable full-screen view in the graphics settings. If you run with full-screen setting, the KSP window disappears when you switch to another task. Running windowed with - nopopupwindow option, the KSP window continues to run as if full-screen when you switch tasks. It also allows you to set the window size to your max setting without the Windows taskbar constantly popping to the foreground. This took me a while to figure out, so I thought I'd pass on this tip.
