hey Martin, nice to see you =)

yes, panels are containments with their own view window, just like the 
desktops (so, assigned to a screen by their own)

that would need I guess some special treating in kscreen like
"when you encounter that particular screen (edid? manifacturer/model?) do not 
set it as primary"
or even stricter, set as primary only when you encounter that particular 
screen that is the one you have sitting on your desk, and not any new unknown 
one
