Round Two. FIGHT!
The nav area on elementaryos.org is getting a little out of control. Here are some thoughts I've had the last couple of days.
The top section deals with login and user names.
The bottom section deals with section selection and breadcrumbs. The very last image is the clicked state for a specific breadcrumb.
One issue that's been brought up in the past with relation to merged the breadcrumbs and main nav is random access to top level sections. One way to solve that is to reveal the main sections if a user mouses over the home button.
