I think it would be really useful to have a more context aware workspaces. But that is a much larger issue than just how to display tiles on the launcher. For instance, shouldn't links you open in your Hacking workspace open in the browser in that workspace? What about files you open in Nautilus. Shouldn't those open in the editor on the right workspace? I think so. That makes this issue much bigger, but no less important.
