WailaPE Mod Installer description
WailaPE Mod for Minecraft Pocket (MCPE), Waila (short for What Am I Look At) is originally one of the most downloaded mods for the PC version of Minecraft. The basic idea is to provide a simple user
interface which give the user information about blocks which are being looked at directly in-game. This port is called WailaPE and includes similar but more basic features. It adds a text tooltip
whenever a block is being looked at in-game.
