I could not belive how many boxes I have for my robot project. When I look at the screen it's full like 6 servo, 2 h-bridges, the big camera, radar, voice recognition and the list goes on. I really like the auto arrange feature but every time I add a new component they all get switched around. Now my suggestion is since it is a window box for say the servos how hard could it be to put a minimizing button in the upper right hand corner so when we click it the box is reduced and all u see is the header discription of the component. Now u could have multiple component in a small space. Visually u could see all of components without having to scroll all over the place. Then if u wanted to adjust say a servo go to the minimised box click to expand, do your work and then shrink it again. Now it is only a suggestion to an already great produce and I would not want the software team to move there sights from the Kinect's development but I just thought this might be a cool feature.

It's not perfect but might help do what you want.
But as Lumpy suggested, take a look at advanced vs basic modes. What I've done in mine is turned off auto arrange and grouped all controls, setting the ones needed in basic mode to be turned on and the ones I don't need hidden.
My screen is pretty full, at 1080p resolution but I just about fit it all in nicely.
Advanced user tip: Edit the .ezb file in a text editor and position your controls exactly where you want them, in line with others by editing the x/y values I don't suggest altering the file if you don't know what you are doing though, the chances of breaking the project are very high.
