Two small mods I found quite nice (not much, but not bad, too) by forummember Sorcha Ravenlock :

Adventurer Shop : http://homepage.eircom.net/~cotnfan/…adventurer.htm
Alchemy Merchant : http://homepage.eircom.net/~cotnfan/…y_merchant.htm

I don't know whether the download links still work, though. I had problems the last time I tried to download them, but Sorcha was so kind to put them into an uploading service.

She did a few more Mods, too.
