Bundle Tweak is a Minecraft mod that tweaks one thing about bundles. Items in bundles now always only occupy 1/64th of the bundle, so you can put more 16 stackable items like ender pearls in them, and even unstackable ones like tools! This may feel a bit cheaty, but with Minecraft's awful inventory system it is sometimes hard to organize your inventory well.

Supported versions

Bundle Tweak supports all versions from 1.17 upwards (that's when bundles got added in the code) on Fabric, and from 1.21 upwards also NeoForge. If someome really wants it I can spend time also adding Forge for <1.21, but I have not gotten this request yet.

Here are some screenshots of a bundle with unstackable items in it on different loaders/mc versions:
