Piano - practice hands separately
The ability to practice hands separately.
This already exists....in Practice mode, just click on the hand in the lower right corner.
Being able to practice one hand on the piano at a time is really helpful.
In the practice mode of songs, notes/chords for both hands are displayed simultaneously. Instead, there may be an option to choose only one hand first and practice thoroughly. Then practice the notes of the other hand followed by both hands.
This could replace the "song trainer"-exercises. Those seem to me to be harder to complete than the songs themselves because you can't slow the exercise down and if you pause to figure out best possible fingerings, the options-screen covers the notes.
