More Storage Stack lets you increase your Minecraft item stack sizes all the way up to 4096. You Can Increas Items per stack from 64 to max 4096.
BTW, anything above 127 can crash your game, so if you get any crash after 127. try maxing it out to 127, if still your game crashes then delete the mod.
IT IS RECOMMENDED TO TEST THE MOD IN A NEW OR USELESS WORLD SO IF THE GAME CRASHES YOU DO NOT LOSE YOUR WORLD.
ALso Has Keybind for Config Screen.
