Simple mod that adds two blocks (for now): normal and large meta chest. It has 45 slots (the larger one 91), a simple crafting recipe (requires logs, a chest and an iron ingot), auto-sorting, and the most important feature: Only items of the same tab are allowed. It also features a search system for items in the inventory, similar to JEI and NEI.

-Upgrades (Some implemented, like keep content when broken, extra space, etc)
