As everyone knows stealth in vanilla is just atrociously easy to the point where you can run around like an idiot in broad daylight chain stabbing everyone.

I tried Stealth skills rebalanced ( http://skyrim.nexusmods.com/mods/28418//? ) but I still run into things like a guard not noticing me when I stand on a dock, outside, in plain sight, in front of him.

Sneak tools ( http://skyrim.nexusmods.com/mods/19447//? ) seems to modify a LOT but looks interesting.

Path of shadows ( http://skyrim.nexusmods.com/mods/10456//? ) looks to be good but apparently abandoned.

Any thoughts?
