Great For Training but could be better

Im an audio engineer brushing up on training my musical ear and knowledge. This is really nitpicky but I listen to the ear training exercises with Sennheiser HD 380s and the samples are low quality and could be fixed my putting a simple high pass filter on them (some basic EQ).
I think that it would be very beneficial to have an exercise where you have to click or select all of the notes within a single key such as asking
Q: D Dorian
A: D, E, F, G, A, B, C, D

A cool format is have the prompted scale above in your "question section" with a corresponding scale below without any accidentals (no key signature I would assume for this exercise) and below list the musical alphabet (linear with the root starting on the left) with #s above each letter and bs below each letter (once an accidental is clicked the corresponding staff above places the accidental in the scale so to have a visual representation) the student would have to correct the scale by adding missing accidentals.
