Hopefully others will offer their opinions also...

It depends on what kind of guitar you are learning. For classical you will need to learn music notation, then looking at the scales will make sense.
If you are learning guitar chords, there is an extensive library of chords and diagrams for reference (Window menu>Guitar chords.) And guitar chords can be automated to show when you are playing a song chart. Choose a very slow tempo and loop a couple of chords you want to learn. You can also set Chord anticipation in Prefs, so the diagram appears before the bar so you can get your fingers there before the first beat of that measure.
In the Guitar chord window is a button to toggle between the chords and library. Nearly every chord has a few different diagrams up and down the neck. Do not get discouraged from all the different possibilities of chords and different diagrams! Just learn one or two at a time. It can be fun using iReal b playing along with you once you have a few chords memorized.
