im specifically looking for stealth takedowns and non lethal fighting styles to be added in the future. its how i play in thief, its how i WANT to play in skyrim.
For that, I think you might be interested in my work in progress Sneak Tools mod. It's really a work in progress though, and I currently have little time for modding and plan to just wait for SKSE to make a public release anyway so I can much more easily script some things, so it might still take a while to be released, but I am working on it
