Hopper Filter [ABANDONED]

Are you frustrated and tired of creating complex redstone item filters that take up space and cause server lag? Don't worry because i'm here.
This is a plugin I made for my girlfriend but I thought you might need it.
Hopper Filter is a plugin that allows you to create and customize what items the hopper can accept. It is extremely simple and easy to operate, you just need to place the hopper, then press Shift + Right-Click to open a special menu, the rest is to add the items you want the hopper to only accept.

max-hopper-per-chunk: 5
chunk-collection-enabled: true
menu-title: "&8Hoppers Filter"
particle: FIREWORK #set "none" to disable
message:
  prefix: "&3[&bHoppers Filter&3]"
  no-permission: "&cYou do not have permission to do that."
  reload: "&aConfiguration reloaded"
  max-hopper:  "&cYou can only have a maximum of %amount% hoppers per chunk!"
  saved: "&aSuccessfully saved filter data."
  open: "&aOpening the filter menu."
