This is my list, not bugs but just things to make them more helpful.

- Not fall behind as much when I am sprinting, I get into fights and they are miles (really) behind.
- Being able to tell them to use ranged or melee, at the moment they switch too randomly.
- Give them a horse too.
- Be able to tell them to back up.
- Give them the ability to use potions.
- A toggable marker in case you lose them while they are alive.

I want them to fix Lydia's marriage. I have become partial to her due to adventuring with her so much. Also, I wish they would do everything you said too OP.
