Hello,
I developed a proof of concept for a small feature in the Movie Clip Editor.
It is a Move to Layer operator, similar to the ones there are for Grease Pencil layer or the Collections. Here is a little video showing it in practice:
I also created a PR here
There are a few things I can’t get to work properly though, it usually works when there is only one spline selected. But when there are multiple splines selected, sometimes some of the splines disappear. There are probably some obvious flaws in my code so if you have any advice on how I could improve I am happy to update it.
Thanks for reading !
