So will Skywind be using the FNIS for custom animations that are more proper to Morrowind's creatures and weapons? I mean, a lot of people uses FNIS to put in custom animations. Heck, someone finally succeeded at putting in Spears and Javelins into the game with custom animations... And many other mods has used FNIS... So will Skywind be using it too hopefully?

Could go either way at this
Could go either way at this point. If you know how to set up the animations that would be great. I would also be open to ideas for implementation.
