I recently tried Canva Video for movie production. Generally Descript is better, especially because of its ability to edit video based on transcript, which Canva lacks, but Canva has one killer feature that I want — the ability to interpolate between two different arrangements (position, scale, rotation, transparency) of the same layers as a single operation, instead of animating each element individually. I think the best way to do this is to allow grouping of layers, which is desirable anyway, then be able to do a custom animation on a group. Once you have groups you can then apply other animations to whole groups of objects — Canva is very good at this.

If there are multiple layers in a template (a music bed plus a VO, for instance), they should be attached together so that, once inserted into a project, they remain temporal relationships when moved. Either that, or we should have the ability to select multiple layers so they can be dragged together.
