Leftist Potions
With the release of version 1.18, Minecraft developers moved the potion icons in the inventory to the right side of the screen. However, experienced players know that this is exactly where item lists from popular mods like JEI and REI are usually located, creating inconvenience when used simultaneously.
The Leftist Potions mod solves this problem in the simplest way possible — it returns the potion icons to their rightful place on the left side of the screen. This is a small but very useful interface improvement that should work correctly with most other modifications.
