I noticed that the hide button is not working properly: When clicked, it makes the bar invisible but leaves the space untouched, which results in a blank space above the site. Very uncool.
Suggestion: make is exactly as hello bar or attentiongrabber: when closed, collapse it and then drop down a small arrow to the right to un-collapse it again.
