About this Mod

This is a Minecraft mod allowing items to stack together in the inventory if they share one of a set of tags. To stack, simply click the target item while holding another item that share one of the whitelist of tags and the two stacks will merge into 1.

By default, this supports any common tag prefixed with ingots/, nuggets/ , storage_blocks/, raw_materials/, gems/, or dusts/, along with several mod specific tags. Additional tags can be added using the config, along with blacklisting specific tags which have the given prefix but should not be considered equivalent.

To aid in discoverability of this mechanic, when holding an item any items that are considered equivalent will have a green arrow icon indicating you can stack them together. You can additionally view all tags making items equivalent in JEI.
