Upsizer – Inventory Tweak Mod For Minecraft 1.19.4, 1.16.5, 1.12.2

This modification will slightly increase the maximum number of items in the stack. But the main thing in Upsizer 1.19.4-1.12.2 is that it works not only for vanilla things, and with the help of a configuration file you can configure the objects function any other mod options.

As you know, some items can take up entire slots, but you can optimize this to save space in your inventory.

Updated to 6.1 version
