Basically, I want to take what's displayed on the desktop when I click the workspace switcher or hit super+s, shrink it down to icon size, and replace the default Workspace Switcher icon with it in Ubuntu 12.04's launcher. I think this'll be pretty awesome if anyone would like to help me see if it's plausible. I figure this would be the easiest way since it just takes the output from expo (unity calls it "spread workspaces") and puts it into a launcher. I just don't know how to do it is all. Any help will be much praised!
