I am considering purchasing. But please do your best because it is one step more functionally insufficient.

The first impression that I tried using it is not bad.
Environmental sounds should be customizable with mp3.
I think it's better to be able to customize the background so that it can be dark.
I'm sorry for all my hopes.

Good luck with development.

Thanks! We are working on making it better, and all feedback is immensely useful and we’ll tailor it for you if you use it. You can become part of our development process! We’ll look to add dark backgrounds and ability to change and add your own audio. At the moment, I am working on the desktop syncing application you mentioned before.

I read the books with my audio on the background. The programm is called nullnprojects.
