I'm kinda bored by primitive life of npc's in towns, and would like to have more life in there. I remember a mod which added some life timetable to characters and allowed them to enter and leave buildings. But, back then, it was in early stage and only for Balmora. Maybe now we have such mod, in final stage, for whole game + addons, and which won't conflict with community patches:

Morrowind Code Patch 2.1MGEXE 0.9.10Morrowind Patch v1.6.5d_betaWestly's Pluginless Head and Hair Replacer

There are two mods I know that does that. http://mw.modhistory.com/download-87-7944 and http://download.fliggerty.com/download-113-105.

LCV moves the NPCs around from homes at night, shops during the day etc.Its more thorough, but doesn't cover all the towns.

Grumpy's mod just disables NPCs who are outside during the night, but covers more towns than LCV.
