Increases the size of the player's inventory
About this Mod
Increases the size of the player's inventory and hotbar.
The inventory now has 90 slots (up from 27 in vanilla), and the hotbar has 18 (up from 9 in vanilla).
The expanded inventory displays in all vanilla and modded guis using an automatic patching system. Behaviour can also be customised per-inventory via a config file to manually add support for modded guis.
