first of all thanks for your great product and the great value it offers and also consistently fixing and improving it. You have my deepest respect and appreciation for that.
Here's my proposal:
Right now for scale identification (in selfmade exercises), you can only set it to ascending, descending, random, and sounding together as a chord (the last one is a bit of a headscratcher to me, to be honest).
One thing it doesn't feature, which regularly comes up in conservatory exams, is having a scale played back in e.g. ascending thirds.
Wouldn't it be fun, if you could also practice this with earmaster?
