Please refer to the original mod's description as behaviour is unchanged: https://www.curseforge.com/minecraft/mc-mods/better-placement
In short this client side mod tries to improve vanillas block placement by allowing a block to be placed when the cursor moves to a new block position instead of a block being placed every 4 ticks.
There is also an option to only allow this modification whilst in creative mode.
Note: Mod jars will work on both forge and fabric.
Thanks to tterrag1098 for initially authoring this mod.
