Different Accuracy Rating for Each Finger

[L-Prime]

Is your feature request related to a problem? Please describe.

My two left fingers are definitely worse than my two right fingers but I wonder by how much. Is it bad enough that I specifically need to practice to even them out? On top of that, are my outside fingers worse?

Describe the solution you'd like

If I could see my accuracy rating for each key, I could tell which fingers are worse and by how much.

Describe alternatives you've considered

It would also be cool if it had a left versus right mode, an inside versus outside mode, and one that I can just see each individual key's accuracy. I could have this data for just one song or maybe over the course of a longer period of time to get better data.
