Question about hiding in forests

[Flanker90]

New guy here. I was hoping someone could definitively tell me how the hiding mechanic works in this game? For example, if there's a long rectangular forest and my Elves hide in one end, can the other army see my units if it enters the opposite end of the rectangle or must they be closeby? Also can the enemy army still see my units if they disengage from a fight to take cover in a forest?

These are the only questions I've thought to ask until now - there may be more. If you have any further insight to drown me in in addition to the giant wave of new information overwhelming me since yesterday, feel free to share!

THIS GAME HAS SUCH A STEEP LEARNING CURVE BUT I LOVE IT! Actually I love crushing and enslaving weaklings, but I suppose it's all the same in this game.

It's a matter of distance between units. If it gets close enough it will spot them.
Also some units are better at spotting than normal, like lizardmen having predatory senses.

If a unit is in a forest and far away enoug hfrom any enemy it will be hidden from them.
if a unit that was visible go into a place where it can hide like forest and is far away enough from all enemies it will turn hidden.
Also if a unit cuts all line of sights with enemies (like moving behind a hill, as being in a forest is not cutitng line of sight by itself) it will become immediately hidden until one enemy has them in line of sight again.

its range based afaik (lizardmen have a trait that boosts that range)

they cant still see them, but they'll know where they are since they'll have seen them disengage and go hide into the forest so they could make a good guess

Basically, when you hover your mouse cursor on a forest or trees, you should see if there is a tree icon next to it. If there is, your guys can take cover in it but your have to make sure that most of them are in. When you see an eye icon on top of your guys, then they are hidden.
