First off Scaler (nearly) replaces all the other tools I use for production for writing music and it is great just how it is. Thank you so much for adding a guitar display as I use both guitar and keyboards for writing so that was perfect .
Anyways, one concept I use frequently when writing melodies are the intervals of the scale for the key I am playing in. I would love to be able to toggle the Note Names in the top display to instead display 1st, 3rd, 5th, 7th so that I can more easily find the main arpeggio notes for the chord the tool is currently displaying. This would help me greatly in melody writing and simply using the tool in general. In my imagination I even see them color coded, red = 1st, green = 3rd, blue = 5th, yellow = 7th so I am able to quickly reference them at the moment I see them on the display.
