Here's a list of updates I think everyone would be happy to see.

Invincible Shadowmere
Invincible Pet Dogs
Remarrige
Invisibility without 5,000 limitations

Why do I want these things?

Shadowmere died falling off a cliff.
Vigilance was KIA
My wife was annoying so I had a DB follower, kill her.
Invisibility worked much better in Oblivion.
