Great app! One usability issue in latest version – Muscles & Kinesiology Review

I have been having longstanding problems with back and neck pain, and have found Muscle Premium a really useful way to understand my body better, using the wonderful 3-D interactive touchscreen UI. One usability issue in the current release (5); the older version had a menu item called "full musculature" which showed you all the muscles of the entire body at once. That feature still exists in the current version, but is hard to find. The user has to select any specific muscle, then click on the ">" in the top left hand corner of the screen. This will open a drop-down menu, with the first item being "Muscular System". Click there, and you can see the whole body again.
