Vertical space is always at a premium, especially on smaller displays like netbooks...
Can I suggest moving the #div.primary-breadcrumb up to the div#headerContent area and lose that white space the breadcrumbs are eating up?
In other words... Move the title of the workspace above the tabs, next to the logo and move the tabs all the way up... There just seems to be a lot of dead white space in that area.
Between browser tabs, bookmark menus, then the Company Logo / Header banner that adds up to be alot of screen real estate we're losing.
Thanks!
