I would like to see religious units of religions which are not mine and my religion.

Green - for units of my own religion
Shades of red or other colours - for units of other religions

Why?
So I can more easily hunt down enemy apostles, missionaries, gurus, etc. ... . Sometimes it is hard to spot them among all the units.

And it would be cool if the religion-hotkey would cycle from no lens to the religion lens and then to the religious units lens.
