would be great if this was able to show current charge och held tool from TechReborn (1.16 Fabric)

Sorry, I never played TR, and just downloaded it and read about it in the wiki.
You're talking about the tools like chainsaw, jackhammer, etc., right?
And those don't have normal durability, so there's nothing to display for them, normally, as I see it? So we could have the energy level instead of the durability, for them?

I posted a version 1.8.0 to CF which should work with TechReborn, as far as I can tell. Please give me feedback about this.

Works like a charm 👍 😃 good job.
