Suggestion: Ability to unlock letters when reaching a certain score instead of certain speed

[Dev2150]

I can just force myself to type faster to unlock letters, how about having the ability to choose to unlock letters if you're just good in general - quick and accurate? It would be cool to choose this in settings.

What I do now that I improved substantially:

• Reset the statistics (not everyone likes that)
• In the settings
  • set "Tartget typing speed" to a reasonable value that matches my real typing speed
  • slide "Unlock additional letters" completely right/up
  • slide "Add words to lessons" completely right/up

Now I type an initial lesson with a lot of letters, which calibrates roughly 2/3 of all letters. After that I continue to calibrate more letters (maybe with "Add words to lessons" tuned down completely).

As a result I can get to the sweet spot and right training letter for my target speed within a few lessons. Usually takes less than 6 minutes, which is just the right time for a warmup :-).

I do that on every computer I happen to come across when I want to train, which saves me taking care of an account and also allows for nice training on bad days or unfamiliar keyboards.
