Flexible credits screen for renpy

I've always tried to make a credits screen that's both nice while remaining flexible. Over the time I've had few tries with different ideas, but none of them satisfied me.
Finally I sat down and wrote one that I can customize as much as I want, add or remove names, text or buttons without worrying about messing up the timing and animation.

There are few changes I want to add and few ideas I want to try before adding it to my GitHub, till then it will be available exclusive for my patreons: https://www.patreon.com/posts/flexible-credits-31311726
