Describe your suggestion:
Currently MysticalWorld adds a bunch of ores and "vanilla likes" tools for it.
I want to disable everything because it is duplicated with other mods.
And some are unnecessary.

Describe alternatives you've considered:
Currently two options:

• remove the mod from the list
• clear dimensions = [] and disable all items with crafttweaker (rather unattractive)

You can also disable the ores by setting the spawn chance/count per chunk to 0, they should no longer spawn. This should be indicated in the configuration comment.

However, I have no intention of doing any sort of conditional registration. You're welcome to disable the recipes and use JEITweaker to hide them from JEI, but I have absolutely no intention of making it so that you can completely remove things from mods entirely from registration.
