It's really fast, and I think epub is better than pdf so this app is a good way for making ebook rather than using latex or word applications

There is no portable version of the application on GitHub, only the installable one. The project owner prohibits the use of GitHub for issues and discussions. They say, "we need to give everyone the opportunity to participate in discussions - through our own forum." Personally, I am not so interested in the development of this application to register on a third-party platform just because of this. It would be possible to compare the number of registered users on GitHub and on their forum (when it was created or even now, after years of its promotion) to close the question of the forum's competitiveness). Or, if you like, compare the number of legal users of Microsoft and the forum to come to the same conclusion.
