Understood. BUT if you are a mainly one-database user, u can consider turning off the side bar. You can still see inbox and tags within the list view by enabling the relevant options A very nice touch on sorting groups in list view. Nor you need the inspector to be on all time to save the horizontal space. There are quite a few discussions on 3-pane view in DT2 vs DT3 and u can search for it to see how different users are getting to like the current setup as they use the system more. Obviously, not all users are the same.
