The Anim8or UV tool is a quick way to control an object's UV coordinates, and as such is never going to give the same level of control as an outside unwrapper. It is quite effective with simple geometric shapes, and the ability to control UV mapping for individual faces is handy, but for complex organic models UV unmapping is the way to go. For example, a simple model like a plank of wood will have texture stretching on at least 2 faces, most likely the ends, by default. The tool in Anim8or can very quickly adjust the mapping for these faces and with a bit of practice can be very effective. It's simplicity does mean it is also simplistic, but compared to the impenetrably complicated and downright daft UV mapping controls in Carrara it's amazingly awesome!!!
(BTW, well done on completing the tutorials, if you have made it this far you have passed the most common obstacles. If you have successfully made an object, rigged it as a figure, constructed a sequence, and tied it all together in Scene mode, you are officially no longer a 'Newbie", despite what your status says!)
