Hide top row in Dashboard view?

We are currently testing out ES 2.1.1 and Kibana 4.3.1. We currently use Kibana 3 to to power an 'ops wall' where space is at a premium and the new top row is significantly bigger than the one in 3.

Is it possible now or can I request that there be an option to minimize the top row for when you just want to see your dashboards?

There isn't an option to hide the header at the moment, but we do have a feature request open for hiding the bar altogether when embedding a dashboard: https://github.com/elastic/kibana/issues/5350

Thanks, I will keep track of that issue
