Not sure if this belongs specifically under the Left Navigation Theme or if it should just appear under the general Confluence section for bugs. Anyway, when using the extra Navigation page with the Left Navigation theme ( http://confluence.atlassian.com/display/DOC/Customising+the+Left+Navigation+Theme ), there are gaps between the headings. You can see the gaps on the old Codegeist site: http://confluence.atlassian.com/display/CODEGEIST/Atlassian+Codegeist . Notice the gap between "Atlassian Codegeist" and "About". In Confluence 2.6, these headings all appear with no gaps. In Confluence 2.8, these gaps start to appear.
