@zordid, I think the issue with notifications only appearing on the top right monitor is probably logged already. Just don't know the bug number.
@xjcook, Yes having a launcher in the middle of your monitors only really works if you have it set to never hide. I suspect someone might have already logged that bug back in Ubuntu 11.04 when it was still possible to put the launcher in the middle of the desktop.
