Axis Labels were requested before & the solution was the colour-coordinated axes. I use various programs with colour coordinated axes and they are not all consistent, but they are all labelled. Labelling the current origin & component origin axes is not a great solution too because they are off by default and also sometimes hidden by the geometry. A reference triad that rotates with the model--Even something in the view cube--would quickly let the user get his/her bearing.
