Makes your character turn towards whatever you're mousing over. Best thing for multiplayer where you can see what your friend is currently looking at / operating on.
Based on an old Searching Flashilight mod that did the same thing: https://mods.factorio.com/mod/searching-flashlightR
Updated to work with Factorio 1.1. Changed the name to allow for reupload.
Credit goes to Xagros for the original idea and code.
