MATE on dual screen, put a panel on secondary screen?

[Fred Smith]

hi all!

Experimenting with dual screens on F20 using MATE. Video card is Nvidia 9800GT 
using Nvidia drivers from rpmfusion:

kmod-nvidia.x86_64 1:331.113-1.fc20.5  @rpmfusion-nonfree-updates

So, I've got it configured, using the nvidia X-Server Settings tool and it
works nicely sofar.

But I'd kinda like trying it with a set of panels on the second screen much
like (if not identical to) those on the main screen.

But so far I've not figured out how to add a panel to the second screen.
The context menu (right-click on a panel) for "new panel" offers no options,
it just sticks it on the first screen. I can't drag it, it just seems to 
want to sit there.

Can someone advise me if thereis a way to do what I want? some arcane
incantation on the commandline, perhaps?

thanks!
