scale how long does it take to open a new letter

[tilers4you]

I am immensely grateful to the developers. I use the trainer every day to practice my skills. I can see all my progress. But it would be great to have the ability to see how much time I spent on learning each letter. For someone who studies persistently, this information would help to work on letters that take a long time. Although it's already clear when you get stuck and feel a letter is not coming easily, such statistics would be interesting. You may have time to implement such a function. Thank you very much for your service!
