I am surprised that such a simple feature like z-index control is not natively available in Edge Animate.
Just think of a simple animation of some cards overlapping each other and you want to bring one of the cards in front when hovering.
So please add this feature as a keyframe able value on the panel or at least as an action.
I do not think that this would help in most cases as the z-index would need to change on some event. I suppose you do know to use css for it.
yes I do know how to do this with css, but than I have to switch to
scripting insted of using keyframes.
