not an issue but I would like it if you backported to older versions, mainly 1.12.2. :)

DIY, if you can't then don't open an issue to ask the developer to do that.

I have no idea how to request features so I did it in the issues tab, also I don't know how to code, I'm just a Minecraft player.

It's really hard, like hard as hell. Bring it on 1.17 is already a nightmare. Now 1.12 requires a lot of work or even impossible since there's only one man doing this project.
