It makes it so shift-click doesn't stack items into containers or out of containers. This feature is changed to alt-click instead but it doesn't just move what you click on. It moves all objects of that type in your inventory. On top of that. Conventient Inventory considers all the IC cables to be the same item. So if you alt click copper cables into a chest it takes all cables, gold, iron, tin and then some tools and move it all into the chest or out of the chest.
It also considers all redpower items to be the same so alt clicking some nicolite into a chest also moves all sapphires, emeralds, rubies, tungsten and so on into the same chest.
The alt key also hangs up when you alt-tab out of the game so just clicking an item will move all of them into and out of chests. Or in my case clicking a uranium cell moved all the cells in my inventory into the reactor. Causing the cables to burn and a transformer to explode. I talked to the author and he says that this is mojangs fault and not his and he seems content with that "solution"
No such jar. There are 4 jar files in total in the minecraft folder after installation.

I also don't see why this mod should be included without any option to disable it.
