On my dual-head setup at school, I often find myself using workspaces in combination to accomplish some task---e.g. having an emacs window and related things open on one workspace with firefox on the other workspace to refer to some information. While working on the task I want to consider the two workspaces as one "meta-workspace" and be able to quickly switch to it as a whole without thinking about the individual workspaces comprising it. Sometimes I have several of these "meta-workspaces" at a time. So I whipped up a simple new contrib module using extensible state for dynamically creating and managing such workspace groups. I've pushed it to the repo, hopefully others with multi-head setups may find it useful as well. As always, patches and suggestions welcome. -Brent
