Something I think would be great for Wick Editor’s tweening feature is to separate rotation, position, and size movements rather than group them all into one tween. Examples I can think of are Alight Motion’s and Toonsquid’s tween feature.

See how there are multiple keyframes for position and rotation for the fur tuft? This is helpful for creating drag movements on a character for hair, fur, clothing, etc… it’s something I’d like to achieve on Wick Editor since I have fun tweening characters as well!! :)
