Features:

• Blacklist/whitelist with full java regex support*
• Hold crouch to disable vein mining

• Even modded ones I think?

Cons:

• It's very unfinished

*Forge's configuration interface was lost somewhere around 1.13 and has not yet been restored. Customizing the list of ores requires manual hacking of the config files.

It's MIT licenced, do whatever you want.
