Let's begin with the small things!

Glow Wool!

Rather an simple thing that are crafted pretty easly with glow inc sacs 
 

Leaded Glass

Fun fact: A friend of mine wanted me to add this

Dripped Moss Block

I added this so the Mossy Sand stone makes sense!

Netherrack/Red Netherrack/Endstone/Basalt/Purpur And Blackstone

The only reason I added this, is because it felt right

Pretty basic too, also you now have to craft End bricks with the Polished End Stone!

And Smooth Netherrack, for that put the Polished Netherrack in a furnace instead of Netherrack

Mushroom Bricks

It May be good for Mushroom Island houses!

Wooden Lanterns

They come in all types of Wood! And they also have an Roof variant!
They also have a soul Variant!

Soul Sand Stone and Gravel Stone

C'mon, why isn't this in the game!

Prismarine

I was shocked to find out there was no Chiseled Prismarine in Game!

Tuff, Calcite and Dripstone Blocks, Granite, Diorite and Andesite Blocks

Again, why does only Stone/Deepslate have so many decoration blocks and not them!

We all were sad when they didn't add them, let's be real here!

Bookshelfes

Very basic, yet they are pretty nice

Quartz, Morion and Hematoid

Hematoid can only be crafted while Morion is found in the End!

Gold And Copper

I promised the Bars would come!
They also have a soul Variant!

And that is about it!
You can also use the Stonecutter to get some of the blocks:
 

I hope all the Builders that see this are happy!
Anyways have a nice day 😀

I found a Chart on Reddit, which shows most block variants!
And I decided to add the blocks from this addon to it!

My version:

And I also made a Video for the Addon!
