Launcher disappeared, how do I restore it? I mistakenly dragged an icon on the home screen (Nexus One) to the bottom area ("Main dock") that contains 3 main icons (phone, launcher, browser). 

That icon replaced the launcher and now I can't access any of my other apps.

(My launcher is the ADWLauncher, that comes with CyganogenMod).

What do I do now?

How do I revert this back?

(I tried "Restore ADW settings" but unfortunately there was nothing in the backup location).

Is there a way to "restore it to factory settings"?
You should be able to go to Settings -&gt; Applications -&gt; Manage applications, find the launcher, and Clear Data for it.  Hopefully that will restore it to default.
