Give setting for font size of key note labels

[sreich]

My primary workflow with this app is having the web interface connected through my tablet. However, the main UI elements that have difficulty are the ones on the piano keys themselves. The ones above the notes that show the name and the ones inside the notes that show the degree. As well as the labels at the bottom of the keys

To me, the most important one is the note names on the top of the keyboard... All in all, these labels are really small even on my A4 sized tablet screen, like text for ants...

To be honest, they're even super small on my desktop monitor. Especially relative to the other UI elements

If you find ways to address these issues this would be huge for me, it's really the biggest complaint I run into these days. Other than that, this thing is serving me so well, I love it. It's really been helping my piano learning journey tremendously
