Remember, the best way to get mods that alter the same leveled lists to work well together is by using Wrye Bash.
This can't be all there is, though. So if you know of mods that qualify--mods that add any amount of well-balanced equipment or other various items to leveled lists, or otherwise integrated into dungeons or on NPCs, and not just in a chest or on vendors--please share. I'm specifically curious if there are any more mods like this covering clothes, and especially clutter, in addition to the typical weapons and armor. But of course all suggestions are welcome. I hope this list is helpful--I'm sure there are at least a few people out there who want to expand and diversify the selection of items in their game without committing to a serious overhaul. If anything, maybe this sentiment can encourage more modders to integrate their great work more thoroughly into the game, should they have the resources. But hopefully this list will grow enough I won't be asking for that for a while

Thanks!
