When I select Projects, and then select a particular project, I no longer have any breadcrumb navigation. To get to another project I have to click on the Phabricator text to get back to home, then I have to select projects from the menu to select another project to look at. It would be easier to have breadcrumbs at the top of the project page that I could just back up to the projects home in order to select another project to view. This same problem exists elsewhere throughout the app. A good breadcrumb system would let me move around the app and backup to any stage quickly by using the breadcrumb navigation.
