Like the title says: NoWorldBobbing, I would really like a module that disables the world around you bobbing when ViewBobbing is turned on, so only your hand moves around, many players don't use ViewBobbing because the world around you bobs which is annoying, but when it's the hand only it looks really good.
Some pvp clients like Badlion Client have it and it's really cool.

I know that it would be better if it was included with tweakeroo, but after extensive searching for a mod like this with no success I ended up making it for 1.16.5. Here it is if you want to try it out! https://www.curseforge.com/minecraft/mc-mods/no-view-bobbing-screen-shake

There are already this feature in the newest release I think in the tweakNo
