please life bar above the boss, same as with mobs

I play a minion build, and many times I am against a boss and between explosions, fire, my own minions, I don't see the boss, if you can put a life bar on top of the head, so that I can locate it, it wouldn't be bad at all, it's something that shouldn't be very difficult to be able to put, in the options as an activatable option, I understand that now you will be saturated, but for the near future, it wouldn't be bad
