Really impressive but please make it easier to navigate!

I have this app on my ipad as well and I will say it is much easier to navigate the model on there, I can’t seem to move around the view to different parts of the body easily! Please take heave to the multi touch function for the app on mac and make it easier to shift. The fade is also a little faulty its hard to see what i clicked on when the whole thing fades because the selected item is highlighted as well. Please fix in the update! Thanks
