You can grab the yellow bar below the title-bar and dock it to other windows (the blue shaded area in the source view shows you where it plans to put it, for example). Each is a separate window (like LabVIEW toolbars) but you can dock and nest. I really like the way Codetyphon/Lazarus works for toolbars etc. What you can't do is dock to the top and bottom of the desktop or dock the context help or dock windows to each other. You can kind of do the above by docking palettes and Project Explorer to the desktop sides (which is what I do). I also don't like the menubar only reflecting the currently selected item ala Mac - it trips me up all the time. I like to view multiple VI diagrams and panels when debugging and editing. Maybe similar to the ribbon interface and how that was only really used on the Web UI builder and an alpha. I'm guessing they had usability issues or something as it obviously didn't end up like this. It took some digging but I found an old LabVIEW 8 beta that had a similar design. One of the key differences in the IDE with NXG is the single window view.
