First release, mostly a proof of concept but works as described. There are extra methods available to call from the papyrus API that could allow end users/other mod authors to create more behaviors without updating the source, but it should provide a good foundation I think.
Installation
Extract the addon.zip and drag the sexlab folder into your Pantella repository's addons folder. And install the PantellaSL.zip file in your mod manager like any other mod.
