Fores New Idles in Skyrim - FNIS 7.6  

No custom animation possible for Skyrim? Wrong. FNIS Behaviors allows other mods to add different types of animations to the game: idles/poses, sequenced, arm offset, furniture, and paired animations, killmoves, and creature animations.

And, with the demonstration mod FNIS Spells the user has a means to display almost all animation files. Dance animations included.

Note: You will have to run a generator tool GenerateFNISforUsers.exe (part of FNIS Behavior) every time you have installed or uninstalled FNIS, or an FNIS based mod. In addition, when you uninstall a mod that uses FNIS Creatures, you first have press the "De-Install Creatures" button, before you run the "Update FNIS Behaviors"
