@pagyew Hi, i hope your holidays was great! I just want to ask you, do you plan to keep working on this task, or we can finish it by ourselves?

@vvtimofeev Hi! It seems that it will be difficult and unproductive for me to continue, since I am not familiar enough with your project. So it will be better if you finish it ourselves.
But thanks for the opportunity to contribute to your project! :)
