Why would you possibly want to do that, you might ask? Well, a practical reason would be in testing a mod. But the more likely reason is for nostalgia, since this was the standard behavior in Minecraft 1.2.5 and earlier. There's a distinct difference in walking through a bunch of items and hearing the rapid item collection sound, as opposed to picking up a couple or so item stacks. Some people found the older method more rewarding when mining, which this brings back.

As of v1.1, you can type /toggleitemgrouping into the console to toggle this behavior.

This mod adds most of the light sources form Amnesia: The Dark Descent and A Machines for Pigs. It also comes with some extra stuff like Oil Barrels, Tinderboxes, Lantern Oil, ect...

Since its a dynamic light mod it can cause some lag to fix that use Optifine or FPSPlus+!

The vanilla torch recipe is replaced, but you can still get it in creative.

Current light sources:
-Candle Holder
-Lantern
-Bullseye Lantern
-Flashlight
-Miner Helmet
-NEW vanilla torch
-Unlit/Lit Torch
-Unlit/Lit Chandelier
-Unlit/Lit Roof Lantern

The Guide Book:
There is a Guide Book in the mod what covers every single thing about crafting and usage.

CRAFTING:
For the Guide Book just craft a regular book with a piece of fat.
To get fat just put any raw meat to the crafting grid.

Tooltips
All blocks and items added by Artifice have tooltips which show their function, and any other relevant information.
Artifice adds several categories of items.

Frames
Frames are basic building blocks that are used as components in other recipes. They come in four tiers.

Blast-Resistant Blocks
These come in solid and transparent varieties, and they have connected textures.
Blast Walls
Glass Walls

Scaffolds
Scaffolds are cheap blocks that can be quickly stacked and climbed, very useful for construction. Left click on a scaffold with a scaffold to stack upwards, right click to place normally. You can build out to the max overhang of each tier in any given direction.

Sledges
Sledges are tools used to smash crafted blocks down into pieces, with a chance to lose different pieces. They have a quarter of the durability of normal tools, and they can also be used from dispensers.

Boxes
Boxes are storage items that allow you to store up to 8 of any item per box. They stack, and they fully support NBT data. Right click to open a box, shift-right click to open a whole stack. Dispensers can use boxes.

Flowers
Four varieties of flowers are added which can be crafted into blue, black, brown, and white dyes in the same manner as red and yellow flowers. A recipe for green dye from yellow and blue is also added. Lotuses will open and close in response to light levels as a bonus.

Lotus lilies are also added, which are similar to vanilla lilypads, and have no related recipes.

Basalt & Marble
Basalt and marble generate in the world, with a variety of generation setting that can be configured. There are a variety of decorative blocks which can be crafted from basalt and marble, including bricks, stairs, and slabs. All blocks are crafted in the same way as their vanilla counterparts.

Pavers
Pavers come in two varieties, Paver and Antipaver. Each will connect to themselves, but they won't connect to the other, allowing for some interesting patterns. Pavers and Antipavers can be interchanged freely in the crafting grid.
