I know that the mechanic is quite integral to how the mod works, but i am playing with some people that do not quite agree with the harvesting change and the requirements it brings up due to it.
I tried putting in : as the only entry at the breakable list, but that did not work sadly.
(I expected/hoped it to just take any modid : any registery name)

So a config to disable the harvest mechanic would be nice or a way to just add everything to the list by means of asterisks.
(any modid = :registery_name, any block from certain mod= modid: and any block from any mod: :)

I know it is a bit specific and it kind of makes some things redundant, but i don't want to remove the entire mod because it still has a lot of neat things that work without the harvesting tweak.

So I am open to adding this, but I would reiterate (as you have already said) that it is quite integral to the mod. However, due to the fact that it is technically already possible I will add this.

I am interested, what kind of requirements are you speaking of? If there are specific concerns I would like to know, to try and minimize them some other game play related way.

Harvesting requires the right tool. Making an axe in the mod is first done by making a flint axe by default or by enabling the vanilla recipes again, having planks and sticks.
While i reason that flint is pretty easy to come by at the start, i am working with people who are... unconvinced.
And you cannot get planks unless you cut wood, which you cannot punch.

Tl;DR i am trying to keep most of this mod in while having to butcher vanilla tweaks due to my friends being hung up to vanilla ways. I cannot convince them otherwise and i don't want to get rid of this mod but also not play without them.

I thank you for wanting to add the feature. Makes it a lot easier for me to not have to lose this mod completely.

So you are trying to use this mod without any of the vanilla changes. Well that is an interesting use case.

"notreepunching:*" -> Any block from mod id "notreepunching"
"*:stone" -> any mod id with registry path "stone" (?)
"*:*" -> probably the one you were looking for
