I am very impressed with the art work and the beautiful look of this app. We are learning a lot of things from the application of all the various layers. I love that you can highlight something and get information and rotate the form to see all the angles. The feature where you can make the item transparent and remove it entirely and put it back is an unexpected and fabulous addition! We are casual users and so not expecting a ton of clinical information, but I think it would be absolutely awesome if it were possible to put the system, or muscle, etc. into motion! I do get frustrated at the sensitivity of rotation. I wish there was a "hold" function where you could freeze a view in place while you look more closely. We have tried to save certain views for later review, but that function doesn't seem to be working?? All in all, I'm loving this the more I use it. Great job developers!
