I only have the trial version, at the moment, but I cannot figure out how to specify an alternate tuning for the guitar fretboard display.
I do see a greyed out "notes" option when I click the guitar icon... is the feature buried under there, but disabled in the trial version?
In the "Answer input" menu there is a submenu called "String tuning". There are many predefined tunings, but also one called "Custom" where you can specify the tuning your self.
The trial version is identical to the full version, except for the time limit.
