A simple quality of life mod that swaps between chestplate and elytra on a keystroke.
The default key is "grave accent" ("²" on the AZERTY layout) but it can be changed in the options of the game.
It can be triggered outside of the inventory and inside too.
This mod requires the Fabric API
Some public servers do not allow this kind of mods and can detect them if it is used in some circumstances (spam the key, swap while pressing a movement key). You should check the server's rules before using it on a public server. I am not responsible for the consequences of inappropriate use of this mod.
