Block Packs
The author built this one for Minecraft 1.20.1–1.20.6 on Forge. On other versions it may install and then do nothing.

Intro
This mod condenses a set of blocks (block, slab, stairs, door, etc.) into a single tool. This removes the need to do any more annoying crafting and uncrafting, and instead lets you place and break any of them directly. After crafting the respective block pack, drop the respective materials on the ground, and by default they'll go into your block pack. Each block pack can hold 4 stacks of the base block.
Controls
Place - Place a block
Use - Breaks a block instantly, if it's one in your block pack
Crouch + Scroll - Select a block
Crouch + Place - Opens the GUI, which makes it as if the block pack was your hotbar
Drop - Drops the selected item out of your block pack
Pick block - Pick block from the block pack
Mod Support
This mod also currently has support for:
- Effortless Building: Allows you to place and break blocks from the block pack
- Additional Placements: Vertical slabs and stairs are treated the same as their normal variants
- KubeJS: Adds an API to add new block packs.
It also adds new block packs for blocks in the following mods:
- Tinkers' Construct
- Create
- Ars Nouveau
- Biomes o' Plenty
