Asynchronous workspace

[Curtis Vaughan <cavaughan avantguardsystems com>]

It doesn’t seem like there is a solution for this in Gnome, but thought 
I’d ask anyhow. So I have 2 monitors: laptop and external. Use Workspaces 
on both. But there seems to be no way to switch Workspaces on one monitor 
w/out switching them on the other. Or does someone know a solution? 
Another option would be to keep the primary static and just have the 
secondary switch. There is an option to the opposite, but that's not 
exactly what I wanted.
