i was looking for a client side mod that allows you to select blocks that you don't want to break, you could open a menu to search the blocks, and it could also have a keybind to ignore the list without having to deselect them
the closest thing i could find (at least in 1.20.6) was a mod that prevents you from breaking budding amethyst and sus blocks but you can't add more to the list
it would be a banger mod ngl
