Multiple Desktops

[Fa310tx]

Is there an application (maybe today screen plugin) that allows you to have multiple desktops that programs can open on? I saw on mobile shell 3 you can have an extra wide lifestyle desktop, but I don't think programs actually bind themselves to the desktop, just the widgets.
I think it would be cool to, say, have 3 programs open and be able to slide back and forth between them, like you would with windows and virtual desktops.
