Customizable Player ESP

Player ESP + is a client-side Fabric mod that highlights nearby players with a customizable colored outline, including players who are invisible or crouching, even through walls.
Press O to toggle the ESP. Press P to open the color settings menu, where you can choose a color, preview it, save or cancel changes, and select from your five most recently used colors. Both keybinds can be changed in Minecraft’s Controls menu.
