There is currently only one killmove manager on Nexus, Killmove Control by TheMrDomino. It hasn't been updated in over a year and it's awfully buggy, especially with daggers. It also doesn't support MCM and uses a book for setting configuration. I already said this on its comments, but I want a mod that allows me to disable all killmoves except throath slice, which I want to occur at 100% change whenever I hit someone from behind undetected. This might actually be easier to do than a manager, so if someone has the skills and is in interested in this idea, then please make one.
