Thank you. Hmm, I'm not sure if this content is really suitable for the core, so I'm currently not positive about merging it. Do you have any additional opinions?

I am a member of many Telegram chats concerning development on Unity and when it came to your library, people highlighted the functionality they lacked, at first I published it as a separate piece of code in my repository, but now I think that this is exactly the place to be inside the core part

In addition, your core part contains extensions for the same TextMeshPro, which was nice, so it seems to me that the coverage of the rest of the packages should also be (we are talking about Localization), as for Animator, this is the basic functionality that everyone works with, but not everyone can write extensions based on your documentation
