Perhaps a option where you can edit the transparency of a layer and selection of objects?
-Making a sketch layer that either is vector or rough drawn and being able to edit the layers transparency.
Possibly a pop up window with a transparency slider for the layer that can be seen taking effect in real time. This could also be applied for the selected are one as well.
Object path auto tween, making a path or curve of which the object follows, perhaps just the whole kwy frame making it auto follow for a set amount of frames…
Those being my lil’ ideas Owo
(btw, I don’t know if these have been requested due to the layout of the website being a bit confusing and me being a noob)
