Hi, thank you for answering me
So no, you do not already have this option, sorry man ^^'
This option hides EVERYTHING! And what I want is to hide ONLY the ennemy position, our character is not blind yes but doesn't have super senses too ;p
During a battle I still want to can see at least my life and the field kill display.
So, for now, yes I hide the UI but no I do not use your system (go in menu to hide, during battle esc to enable, then esc -> menu to desable again.... terrible) : I use the mod called RTS Camera that allowes me to set a toggle key to can hide/show the UI in less than a half second -> far more convenient
