Do you use Gridded Terrain mod

[Elltee]

I have noticed on some screen shots on various CM sites that people use gridded terrain (which I believe is a mod) - this seriously reveals those little folds of cover in the terrain that otherwise you can spend ages looking for.

Does anyone use this when playing or is it considered 'gamey'. To my mind I wouldn't use it as finding those areas myself where I can approach hidden from view etc is part of the skill of the game. On the other hand if there is widespread use of this mod am I disadvantaging myself.
