After playing with the UI of the XPD Dashboard I have found that having the breadcrumbs navigator on the bottom makes a lot more sense, at least it is more aesthetically pleasing then on the top because of my category selection proxy. Really, it would probably look best if I created a hybrid component with both the category selection proxy and breadcrumb within the same view.
Here is a screen shot of the new XPD Dashboard – a lot more room to view the main content – in this case my problem reports.
Since I can select most of what I need from the History button, I can actually use the dashboard without the side teams view – even more space to see the main content. This makes working with the views very easy.
