Had a comment from someone confused how to use this. I've attached a video showing specifically how to do it.
1. Time-line
2. Add layer (animation is option and can work with it)
3. Add my morph (ensure you have it favorited in your Female > Morphs for it to show up in time-time)
4. Add 1-3 (or as you please) key-frames alternating to give a flap effect
5. Click play
The speed, weight (both in timeline and the physics itself) along with drag effect all wings with tweaking.
Ensure your morph box is ticked for it to appear in the list.
