This is a horse companion/pack horse mod. This mods adds a beautiful Ranger type horse, and a strong pack horse that won't leave it's older brother's side, but for a bit of wandering. They act "natural" horses are people too! lol. Sometimes they wander, other times they take a slow walk instead of a run, especially the pack horse, he has a personality that's for sure. Just enjoy them for what they are, instead of having everything bow to your will with the push of a button. They will defend themselves, they will however, in character for a horse, not blatantly attack any ol' thing. They are found by "Wawnet Inn". The Ranger horse can be "tethered" to a tether pole, the pack horse will follow him, and they get a pile of hay while they have to wait, why not?I use the word tether loosely here, I can only do so much with my ideas.. When mounted you can tether immediately by holding "LAlt" while getting off the horse. When they follow and you draw a weapon, they will still follow, but farther away, so you can do your thing. They will help in combat if they are attacked themselves.
Buttons
>>>>>>>

*Special; use "LCtrl" while mounted to see horses health and get an animation! Open saddlebags to see the saddle bag weight in upper left corner.

L SHIFT + "activate"  on Ranger horse == Plant pole and tether horse. (give it a second)*
"Activate" the Pole ==================  Untether horse, it follows again. (give it a second)*
Or just mount him, same thing, you don't have to untie, it's a role play thing.
Movement
>>>>>>>>>
RANGER HORSE
--------------------->>
"W"  ==================== fast walk
"W + L SHIFT" ============  Run
"W + L SHIFT + LAlt"  ======  Sprint
"Toggle 'AutoRun' Key" === RUN LIKE HELL* 
*Can be use for this , but on foot, it bugs with the actual mod if turned on, activating horses will not function correctly with "autorun" on. Not game breaking, they just wont respond till it is off.
PACK HORSE
------------------>>
"E" ========== Open Saddle Bag menu.
The menu has four options, 
1 - Close menu(if you pressed "E" accidentally),
2 - Open Heavy Bags (1000 weight limit), 
3 - Open Ingredient Bag (500 weight limit),
4 - Stop Combat (if by accident you hit the pack horse, this stops the fight.)
FIY, the Ranger horse stops fighting you if you put away your weapon.
If you go over the bag weight limit, which you can, it will slow the pack horse a lot, until you lighten the load again.
If both bags are over weight, the pack horse will not move at all.
You have nothing to worry about with the pack horse, it does it's own thing the whole time.
*this is aimed at role play.
