So, in regards to Milii20's request with the Replacer, it's an awesome block, but like you had stated in the Wiki, with regards to the replacer it's really OP therefore it's disabled by default. But what if, you had to constantly feed the blocks you wanted to replace into the Replacer or it won't replace the blocks the quarry mines? That way, it can't be exploited to be used as an infinite ore generator.

No.

1. There are no ways to feed blocks. Quarry can't find which inventory to push mined items or which to pull to replace the area. If I made quarry accept item from hopper or pipes, it would cause unwanted bugs.
2. The block to be replaced to, will be fixed to the dummy block, which seems like glass. You can change texture with resource packs. This will prohibit you from getting infinite items.

So realistically, it doesn't matter what the texture is? You don't actually get the block? Okay. Works for me.

This is the future view. In current version(v1.0.9), replacer places the same item as the block on replacer.
