Years ago I requested a stealth improvement mod for Oblivion, which was realized beautifully by a modder DuggeDank in Proximity Based Sneak Penalties mod. It was a clever change that imposed sneak penalties to your toon based on the proximity and line of sight information from nearby NPCs. It really improved the stealth gameplay because it was nearly impossible to be invisible directly in front of an NPC. Mod increased the severity of penalties if you were approaching the NPC from the front. Also backstabbing was made more challenging, but it was way more rewarding due to increased sneak multipliers. High risk, high reward. http://www.tesnexus.com/downloads/file.php?id=15025 I think it would be useful if NPCs were aware of collisions from any objects originating from your PC (also your touch). That way they could lose disposition towards the player and abusing them would become more difficult. About bow stealth play, there should be bow sway movement to make it more challenging to land hits while stealthed. The mod for this behavior in Oblivion was made by TalkieToaster: Bow Sway mod. http://planetelderscrolls.gamespy.com/View.php?view=oblivionmods.detail&id=2464
