I forgot the name. What is this Minecraft Mod called?

I had a very helpful mod that I would like to have again, but I forgot the name.

It has the following function: If a block such as. Dismantling a stone block and then stop in the middle, the status of the "dismantling" is reset.

However, the mod made sure that this does not happen and you have almost a few seconds left to continue with the dismantling (very useful if you slip off with the mouse for example Obsidian).

I'm grateful for every answer ^^

I'm not sure, but I think it's multi mine

It's exactly the one I was looking for.

With pleasure
