This mod adds some new modules for your armor for upgrade your inventory size, your health and your mining, crafting speed and more! (Requires Better Power Armor Grid for work: https://mods.factorio.com/mod/Better-Power-Armor-Grid).
Fixed compatibility with the library.
This mod is not projected for my FactorioPlus mods, however you can use it if you want with them (i'll probably integrate this one with them as a addon).
Spoiler: All the modules are infinity stackable! (if you stack a lot of toolbar modules, you will be surprised XD!)
