I'm sorry that sounds bad.
I have developed these libraries for myself, to use them in the App that have been commissioned to me. But I wanted to share them for free with others to give an extra tool.
Even if they are free, I guarantee the assistance and correction of any BUGS.
However, I do not guarantee that I will continue development to improve or expand its functions and methods.
I don't even have the time to expand all the libraries I've developed over the years, or to add the functions that are required. However, I undertake to provide assistance.
