Alexey,
I want to say thank you very much for everything you have done for me.
When I lost my vision in 2015, I was lost in concern that I will not be able to work on my music anymore, which is my favorite hobby and career. You made it possible and I hope your wife understand that you helping me has a lot of meaning and it is very appreciated. To you, programming this is fun, and it is fun for me to test, but also for me, it is the opportunity to work with music again.
