This suggestion is that you create two recipes for every item in the mod, one which requires the Recipe Placeholder item and one that does not. Then, add a config file with an option to put the mod into a No-Conflicts mode which disables the default "vanilla" recipes for those items and requires the use of the Recipe Placeholder item.

I know the Recipe Placeholder item was added in response to #6 but, while I understand @kreezxil's frustration and desire to have this changed, it is ruining an otherwise elegant crafting scheme for the sake of compatibility of a mod that most of your users may not even have. By adding the No-Conflicts mode, this enables users like @kreezxil to have their desired behavior, without inflicting an unnecessary crafting widget upon the rest of us to clog up our inventories.

There are enough wrenches and other such things floating around, we don't really need any more unless there's a need which, outside of the case where the Comfort mod is in conflict, isn't the case for most people.
