Ok, read your post again and appears to have sorted your issue.
one tip regarding tabs, if IE9 style of tabbing doesn't suit you, maybe it gets cluttered, you can always place the tabs under the search bar to give you more room. just right click in the tab area and select "show tabs on a seperate row".
