I'm trying out Gnome Shell in 11.04. You can push the "activities" key to get into the overview where you can launch applications. I like the idea of the overview as an aid in switching focus, but it's too slow for just launching an application. Is Gnome Shell going to implement, or does it have, a way to launch applications (besides the alt-f2 command launcher) that is as quick as Gnome-do?

edit: To be clear, I'm aware of several Gnome application launchers. I'm curious about the Gnome Shell and any packages it includes (not add-ons like Gnome-do or Synapse).
