How to use Arrow Trails Mod
To select a particle you need to be holding a bow and then a gui will appear at the Bottom right of the screen where it shows the current particle. If you click it, it will go through the whole list of particles in the game until it goes back to the start and the gui will disappear when you are not holding a bow in your hand so i hope you enjoy and good luck.
