Adds various complicated and tedius things that will minimize your need to destroy your server with your chunk sized arrays of machines.
Overpowered Armor Bar by LocusWay
Allow armor bar to wrap when wearing better than diamond, plus other tweaks
Overpowered Inventory by Lothrazar
Expands your inventory space to 15 rows by 25 columns = 375 total slots. Also adds four special slots to hold ender pearls, ender chest, clock, and compass. A keybinding is added to use the ender pearl from this slot (regardless of what is in your hotbar). You can store experience by filling Bottles o Enchanting by putting empty bottles in a special slot in the far right. The two buttons on the top right deposit your items into nearby chests automatically. Also includes a 3x3 crafting grid instead of 2x2. Some bits of code are forked from the open source repository at https://github.com/Funwayguy/InfiniteInvo (Which is a completely different 1.7 mod not by me).
