Fast Slot
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
FastSlot is a small quality-of-life mod that changes the default behavior when shift-clicking Blaze Powder in the Brewing Stand.
Instead of sending it to the fuel slot first, the mod prioritizes placing it into the ingredient slot.
If the ingredient slot is full, the powder will be moved to the fuel slot as usual.
This mod is client and server friendly, requires NeoForge for Minecraft 1.20.1 | 1.21.1, and does not add any new items or blocks.
