!! Character Position Indicator
A minor graphical mod that adds a toggleable blinking arrow above Isaac, made in an afternoon after I got annoyed after I kept losing track of him.
The arrows start off invisible, but can be toggled on and off with the Left Alt key.
The arrows have colors for up to eight playable characters (four Jacob & Esaus in co-op, for example), and move with your character’s scale, letting you see roughly where you are even when really small.
Also has optional Mod Config Menu Pure support for changing arrow size and blink frequency (or turning blinking off entirely)!
