TooManyItems Mod: 1.3.2

This week's mod is sometimes nicknamed 'in-game InvEdit.' The TooManyItems mod, also known as TMI, offers pages of blocks and items, including ones not obtainable via Creative Mode. For example, TMI has items such as fire and snow sheets. These items, along with some more, are not obtainable in the Creative Mode Menu.
This mod works in both Singleplayer and Multiplayer. Multiplayer only if you are an Operator. Once installed, press the 'o' key in-game to toggle on/off. There is also an 'unlimited stack' feature. This is accomplished by holding SHIFT and LEFT CLICKING on the desired block/item. At the top left of the HUD, there is a toolbar with various icons. These icons are in order from left to right: Trash, Creative On/Off, Rain On/Off, Toggle Difficulty, Morning/Noon, and Dusk/Night.
If you want to delete your entire inventory, this can be accomplished by holding SHIFT and LEFT CLICKING the Trash Icon.
Another amazing feature of this mod is the fact that it has 'Inventory Saves.' The player can save an entire inventory; i.e. an inventory for building, an inventory for combat, etc. This inventory feature does not work in multiplayer.
