For reference, the 5 positions that span 4 frets are:

Dorian (starting on 2)
Phrygian (starting on 3)
Mixolydian (starting on 5)
Aeolian (starting on 6)
Locrian (starting on 7)
-------------------

I think some people refer to those 5 positions as CAGED system, since they corrsepond to certain chords if played in Open position.

i.e.

C Phrygian (starting on 3)
A Mixolydian (starting on 5)
G Aeolian (starting on 6)
E Locrian (starting on 7)
D Dorian (starting on 2)

My thinking was, that if we show note names for all of them, the entire guitar would get lit up with note names, and it would be hard to see any scale patterns at all. So we just show 2 - Phrygian, Aolian.

Have Fun!
