ideas for 1.21

let us use § like in bedrock
§lfor bold
§ofor italic
and all those from bedrock
also
make it so §l doesnt need to be places in order ( its an bug )
cuz if i use §l before §4 it will not be bold ( i used an mod to override the mc to allow me to type § in mc java )
also for trims i got an idea
if u use an gold trim then it works like gold armor ( cuz if u wear gold then piglins wont attack )
also elytra and tool trims would be cool for the looks
and if posible
add something like leather that u can place on ur tool to make it dyeable
bug 
the invisible piston, sticky piston, buble colum up / down, void air, cave air, air are BUGGED
cuz they dont do what they are supose to do
if its posible to fix it then please do it ( creative tab )
1.21.1 idea
for redstoners
advanced repeater 
       allows you to change the time it has ( in ticks, seconds, minutes, hours )
dyeable redstone and redstone blocks
       dyeable redstone is placeable dyed redstone that doesnt connect to other dyed redstone unless its the same collor, but if its normal redstone it will connect
       if you use an red dyed repeater and put it into an redstone source then it will be still red dyed power ( like redstone power but red ) it will ONLY power red power sources then
block miner
       an block that mines blocks, usefull for an cobble stone farm or something else
       uses an pickaxe with those stats to mine the block
       this block isnt an entity but it can use potions of haste to boost itself ( like an boost ) 
more in next :D
