This may be a feature request, but perhaps the problem has already been solved. It would be great to have the ability to add easing to scene transitions. The stock transitions are very linear, and do not at all look good. In my case, each of my screens are fluid and fill the viewport, so positioning them relatively on a timeline for swipe navigation gets ugly and over complicated rather quickly. The obvious benefit to using scenes is modularity, and you get the visible transition of seeing both scenes during transition for free – however the linear nature of those transitions makes it feel very unpolished. If anyone can suggest a work-around, or if its possible to override the scene transitions using another animation library that would be great.
In addition to scene easing, is it possible to continue a scenes timeline while the transition happens? Currently the transition ends, and then the timeline will begin – being able to offset this would mean you could have elements staggering in really smoothly instead of a mechanical locking feel on the transition.
