The colorizer wand can instantly break through blocks such as obsidian and bedrock, which would normally take time or be impossible to break.

Definitely an issue, I think at least for obsidian it might make sense to keep it the same but I think just disallowing bedrock should work.

Alright. A whitelist/blacklist could work, or maybe a tag. And then the user could add obsidian to the list of they wanted to.

Yeah, exactly though I think there is already a list to disable/enable but I might be misremembering. Been on vacation for awhile. Either way what I was thinking for bedrock at least is if the config option for breaking blocks is active then you won't be able to use any unbreakable blocks.

As for obsidian and other hard blocks I think you should still be able to consume them because they are still breakable. Just with the way it is currently setup I'm not sure how you would make it so that it takes longer which is why I am focusing on unbreakable blocks like bedrock.

Ah, true

Okay, the latest release should now have these features.
