How do I remove the search bar in ICS? Is there a way to remove the search bar from all of the home screens in Ice Cream Sandwich?   I have a Nexus S, which already has a hard-button for search, so the search bar is redundant.  Long pressing on it doesn't seem to do anything useful.
You can't remove it from the stock launcher, it's a permanent fixture. You can, however, install a custom launcher which is based on the stock one like Apex Launcher or Nova Launcher.

You can also disable the Google Search app completely if you want to, but then you won't be able to use it at all (also discussed on Google Groups).
