Occasionally in the heat of battle, if my mouse pointer has moved ever so slightly to the right of the Fire button, the enhanced compass slides into view, obscuring the button. The time it takes to move the mouse so the compass retracts, then more caustiously move back to the Fire button and press it doesn't seem like much, but can mean the difference in an eel going where it does the most damage or not.
I could use the keyboard instead of the Fire button, but I prefer the onscreen interactives. The enhanced compass is fantastic, but it would be nice if it were a little more separated from the crucial and time-sensitive Fire button.
