Rob: you can remove it.
I removed it because I don't use it:
Configure Toolbars-> Location Toolbar (searchbar) and then move the only action to the left.
Apply (Or OK) and it's gone.
Now, for some reason, planet won't get my second post of the day until the next day. Maybe it's a bug on planet, maybe it's on PyCS, maybe it's on PyDS. Beats me.
