Waila

Waila (short for What Am I Looking At) is a quality of life mod that shows information tooltips about what the player is looking at, within inventories and in-game. Waila is also responsible for sorting the Controls Keybinds by mod. Despite its simple premise, Waila is an integral part of GT:NH and it's strongly advised to not turn it off. Features such as IC2 Crops, status of GT Machines and Multiblocks, Thaumcraft, harvestability, energy storage and more are conveyed via Waila. Waila requires NEI to function correctly, using it to display recipes and uses of the currently viewed item.

Waila Tooltips

Usage
By default Waila comes configured to sit in the bottom right hand corner of the main screen. Whenever the player is close enough to a block to interact with it, Waila will show a tooltip. The types of information Waila shows can be configured by bringing up the main menu with (default Numpad 0) > Waila or Modules. Modules adjust settings for supported mods, while Waila has more global configuration options. Show/Hide Waila toggles the tooltips on/off. Show ID:Metadata displays a block or item's internal references, similar to  or Extended Tooltips. Sneak-toggle blocks hides most of the Waila info other than name/block ID unless Shift is held down. Sneak-toggle entities does the same thing for animals/mobs/villagers. Liquids Hidden/Visible toggles between displaying a tooltip for the liquid or the block below it.

Harvestability
The most important data Walia shows for most players is Harvestability. This puts a green checkmark or red X in front of "Currently Harvestable", showing if the current tool/item in the player's hand can successfully collect the block or item being looked at. Waila will also tell what tool is needed if a specific one is required and even the minimum tier of that tool for machines, pipes and ores.

Keybinds
Waila's keybinds are configurable from  and by default are assigned to the number pad digits zero through four.

Limiations
Waila does not display current Pollution in a chunk, Electricity being carried by cables or wires, Ore Chunk status, owners of machines nor coordinates. These and more are handled by the Portable Scanner, JourneyMap and InGame Info XML.
