We are in the process of building more extensive documentation here https://manimce.readthedocs.io/en/latest/. This site just went up today. Unfortunately, the animations are not thoroughly documented yet.

3b1b/manim and manim CE are not necessarily compatible. We are trying to keep it as backwards compatible as possible, but in the future, they will surely start to diverge a bit.

That issue you posted on 3b1b was closed in September 2019. Manim CE was forked a few months ago. So my guess is that 3b1b will behave the same in regards to applying ShowCreation to PNGs. But I would have to try to make sure.

Thanks @tshrpl for reporting and @Aathish04 for confirming. Closing this in favor of #389
