Zanzibar,

feature is your friend. Use always when you can instead wasting space.
As for your no:
Really, i expected some imagination than a simple no. If you are so worried about discovering things by accient, then objects which are supposed to be hidden won\'t have label on them when pointer moved on these. Alhough once found, the label would appear everytime.
But in my subjective opinion, moving with the mouse is kind of searching, so if someone find label then also the object is found.
Of course the label appear only when you are in range to interact.Zanzibar, have you ever had problem with that macro? When there was some item very close near the enemy or its dead ghous was on the ground, or there was few enemies in one place... ?
I\'m sure you did.
And the label isnt only about enemies, but doors (in future) very small items which model you see but arent sure if you are clicking the right pixel. It helps to fnd out if chest is part of map, or it is chest which you can open.
Isn\'t it better to expant this simple idea to your liking, insted of \"No\" ?
