I also remember using one of the companion mods for a bit.

She could heal me, train in a few skills, fought alongside me and if I wanted to she'd stay at home. Came with a really nice house for the two of us too, lol.

Was mostly useful because of the house which was close to Vivec and I believe she made a certain number of potions a day. But the interaction was interesting as well.

But I forgot her name…guess she really didn't mean much after all
