Suggestion: Make the tiled/ single workspace toggle button bigger

[Sean Brady <sbrady gtfservices com>]

 I don't know what you call that UI widget, but it's the one that 
changes the overlay's workspace view from single workspace to all 
workspaces tiled.  I think that should be bigger and/or easier to get 
to.  It might be better to move it close to the bottom right instead of 
the left (right under the plus and minus for the workspaces) and much 
longer (like a spacebar).
I have found that I am using fullscreen view in apps more and more, 
because I have that great little button to switch between workspaces and 
workspace view if when need to.  I am also keeping more workspaces open 
and using more of them as well, separating them by task.
Another suggestion would be to have an application's window appear on 
multiple discreet workspaces simultaneously.  For example, Firefox on 
workspaces 1, 3 and 4 but not workspaces 2 and 5-8.  Not sure how that 
would be done, but it's something to think about.
Thanks all...
