Custom blocks that give effects, particles, sounds, or knockback

Plugin category: Fun, General

Suggested name: Custom Pads

What I want: I want a lightweight plugin that lets me create blocks that will give a player any combination of effects, particles, sounds, or knockback. I would like the blocks to only work if they are above another block in the config, like a lit redstone lamp. I also want the blocks to be able to support several things, like 2 effects, 5 sounds, and one particle. The blocks should be able to be created in the config file, so there could be unlimited possibilities, and also be created with commands. I would like the config file to look a little like this:

bottomBlock: lit_redstone_lamp
blocksPads:
diamond_block:
vector: [1,5,6] # The amount of knockback in the three directions, like the direction NBT tag of mobs
effects:
INSTANT_DAMAGE 1 1 # <EFFECT NAME> <DURATION> <LEVEL>
sound:
mob.enderdragon.growl
random.explode
redstone_block:
particle:
happyVillager
effect:
INSTANT_HEALTH 1 10

I would like this to be like the plugin Essential Pads, because that plugin is outdated.

Ideas for commands: /custompads <add|remove> <effect|vector|particle|sound> <thing> # Execute this while holding the block
/custompads stats # see what the current block you have does
/custompads all # see all the custom blocks

Ideas for permissions: custompads.use
