Good but could be better!

Could you please place all different related triad chords together in the test part, plus all Augmented and diminished counterparts? They can be arranged in columns with four rows. At least all different scales of given triad! In this way finding the right one would be more challenging, also comparison helps to learn their differences visually. That would be great if there be a test of chords with the key signature!
Also could you please make the app in a way that when we play a chord using green buttons the color of the related key change, indicating they are pressed?
Also I would rather have one octave, but I can place my fingers properly.
Also could you please add an exercise for all different key signatures? For example showing a key signature and asking to play all of its notes in order? Or identifying its name?
