Animator is in "maintenance mode;" it's not under active development. If you find it's suitable for your needs in its current state (e.g. most of our customers love it for creating + exporting Lottie animations & videos/GIFs) then you should be good to go.
If you find it's missing functionality that you need, then I encourage you to check back in a year or so when we will have the beginnings of Animator's successor for UI component creation & animation.
Between then and now, we're focusing on a design systems collaboration platform we're calling Brandbook (you can see a teaser & sign-up form on our homepage.) Our forthcoming UI component studio + animation suite will be integrated with Brandbook.
