What i would like in this mod is a armor status icons where it shows your armor's durability.
I also would like it to be able to have zoom, shaders and to install it without any trouble with security on my PC.
This already exist.
Here is the mod: https://www.curseforge.com/minecraft/mc-mods/giselbaers-durability-viewer.
If you already tried it, I can assure you it's not a problem with the mod, its more of a "I don't know how to install this" type deal.
The second part also exist, there's thousands of alternatives too
