IDEAS:

REDSTONE:

breaker (mines whatever is in front of it)
dispenser (shoots out first item in inventory, or shoots item into pipe)
sticky piston (pulls node in front of it)
piston in general (if node is falling and piston is pointing up then FLING IT, if detects falling node entity FLING IT)

MOBS:

#1 idea, - make mobs pathfind

sheep

sheep can be punched to drop wool without damage
you can dye a sheep with colored dye and it will change color, then will drop the color you dyed it

pig

disable pig aggression
make porkchop look nicer

ghosts

make the default player model whited out
ghosts can pass through any nodes
ghosts fly around
will follow you groaning about "diamonds", "need food", and "join us"
they will fling you up in the air or punch you
ghosts can drag you down into nodes and suffocate you
spawn with cave sounds
drop soul

node monster

gets built out of nodes in the area
will probabaly destroy you
drops all nodes that it's made of when killed

Exploder

sneaks up on you and then explodes
drops gun powder

Game Mechanics:

xp (edit the node drops code to check if node has tag for xp)
brewing
enchanting/upgrading
magic (wands, spells, etc)
better combat ( sweep hit enemies, falling while hitting deals more damage )

New Themes

mechanics (mechanical tools and machines)

compressor (compresses nodes down)
auto miner (digs whatever is in front of it)
decompressor (opposite of compressor

automation

pipes
pumps
fluid transfer
fluid storage
pipes should be able to move objects quickly

HALLOWEEN!

lava acts like water in the nether but lava in the other worlds
pumpkins
Jack O'Lanterns
corn and corn stalks
decorations
cobwebs
costumes (somehow?)
candy
make grass and leaves orange during the month of October
(Use a simple date check and override nodes)
Gravestones
Graveyards
Candles
candy apples
Soul cake, make with cake and soul

Farming

add fertilizer (pig drops bone randomly)
fertilizer is made out of bone -
fertilizer can make tall grass grow on regular grass
bread - 3 bread in a row
make sandwich with bread and cooked porkchop
fertilizer used on saplings randomly make tree grow (make sapling growth a function)

Fishing

have a rod that you can cast into water
bobber entity which goes under water when fish on line

New Items

These don't seem to fit into any theme so list them all here

sugar and sugar cane (grow near water on sand)
rope and tnt arrows
vehicles (car, powered minecarts, trains)
hitscan flintlocks
bows

Ideas

These ideas are all over the place but are good for future updates

make pistons able to push and pull any node that does not use meta or inv
make pistons able to push and pull deactivated pistons
upgrade minecart physics even more
make torches abm that checks if player in area
make furnace abm that checks if player in area
3d character
make tnt hurt player
rewrite minecart
fix tool rightclick torch placement to replace buildable to nodes
if placed last node put another stack into hand
have falling node hurt player?
add a function to set a velocity goal to entities and then implement it with all entities
^make a value if below then stop?
colored chat messages
check if everyone is in bed before going to next night
also lock player in bed until they get out or daytime
create a function to check if a node or group is below
^ set meta for player so that all mods can use it without calculating it
^ over and over again (saves cpu cycles)
cars buildable in crafting table
require gas pumps refine oil
drive next to gas pump and car will fill with gas
maybe have pump be rightclickable and then manually fill with gass using nozel
minecart car train? - off rail use
automatic step height for off rail use
make cars follow each other
oil which spawns underground in pools
powered minecart car (engine car)
chest minecart car
player controls engine car
make entities push against players

Possible Applications

causes object to magnetize towards player or other objects and stop after an inner radius use for better item magnet?

if object:is_player() and object:get_player_name() ~= self.rider then
      local player_pos = object:getpos()
      pos.y = 0
      player_pos.y = 0
      
      local currentvel = self.object:getvelocity()
      local vel = vector.subtract(pos, player_pos)
      vel = vector.normalize(vel)
      local distance = vector.distance(pos,player_pos)
      distance = (1-distance)*10
      vel = vector.multiply(vel,distance)
      local acceleration = vector.new(vel.x-currentvel.x,0,vel.z-currentvel.z)
      
      
      if self.axis == "x"      then
            self.object:add_velocity(vector.new(acceleration.x,0,0))
      elseif self.axis == "z" then
            self.object:add_velocity(vector.new(0,0,acceleration.z))
      else
            self.object:add_velocity(acceleration)
      end
      
      - acceleration = vector.multiply(acceleration, -1)
      - object:add_player_velocity(acceleration)
end
