Looking for a way to make it easier to tell when there is special terrain on a battle map. Currently i find it very hard to figure out the bounds of the terrain. What I'm talking about is situations like this:

1) Trying to position a long line of units in a forest, only to find out there are random gaps in the trees that you can't see by looking at it, or trying to move from one end of it to the other (maybe only part of it is in your deployment zone), only to have your troops discovered because of these gaps you cant see. The same issue can happen with not realizing a certain area is marshy.

2) Trying to figure out what terrain and other units blocks line-of-site, mostly for the sake of archers/artillary, but also hiding units.

3) Trying to figure out what terrain is tall enough to give a "hill" advantage.

I'm looking for mods that will do any of the following when fighting battles:

1) Hold down a key (or press a button) to hide all trees, buildings, impassable terrain, and instead indicate where they are on the ground (change the color, or show icons that look like unit icons) for a cleaner look at where the terrain is.

2) Press a key (or click a button) to indicate where a unit you've selected has line of site to (all areas of the battle map they can't see are colored, or covered with fog, or whatever) OR Hold down a key (or press a button) to enter "line-of-site mode", and the game indicates when you mouseover an area where on the map does/does not have line of site to it.

3) Hold down a key (or press a button) to enter "elevation mode" and anywhere you mouseover on the battle map, the rest of the map will change color depending on whether its lower or higher (maybe even a different color if it is much higher, or high enough to see over a unit).

TLDR: Anyone know of any mods that help you figure out what terrain is what, elevation levels, and where line of site is blocked by things?
