The mineIntensity doesn't do anything and harvestIntensity works but the vibration is very very weak

At the moment mineIntensity applies only to 'hard' blocks. This will be documented more precisely or made configurable at some point.

As for the (lack of) vibration strength for harvesting, it's historically because this mod was made for fighting maps.

We'll take your input into account for future versions, thank you.
