Adds inventory slots to the player as they get different types of items in their main inventory. Effectively making the first inventory slot free.

This mod should work fine in MP and play nicely with other mods that change the main inventory size.

If you find a major bug or have a request/suggestion, feel free to email me at, as I will notice it faster than a post on here.

Based on Moffmaster's idea.
