Suggestion

Option to add one line to remove everything from any mod in question by ending the mod with .* and everything from that mod gets blacklisted.

Example 1
Minecraft:.*
And now every single item from the minecraft is now hidden for users to search up.
Example 2
Alexsmobs:spawn_egg.*
This will only remove spawn_egg types from alxesmobs from JEI information, but still show the rest of alexmobs items and other spawn eggs from different mods or from minecraft itself.

Please don't hesitate to ask for more explenation. I would be happy to help regarding this even thought I have no experience with coding.
