you are right currently we don't support any kind of transitions/animations in Antetype. We are currently working on version 1.7 which mainly focuses on our web viewer (if you are interested you can register for our beta-program at http://antetype.com/beta).
When this release is finished we want to add animations and improve our interactive features. We are still in the planning phase, but the transitions you mentioned are on our plan.
Thanks for posting the feature request!
Thanks Felix would love to try out the beta with the web viewer functionality - just applied.
Just want to quickly second that, as I found this page while searching “antetype animation” on Google. Antetype is already doing a great job in visual design capacity, by adding animation/transition feature it is gonna stand out so much morein building a hi-fi ux prototype. So, please please!
UXPin (uxpin.com) has the most intuitive animation experience for UX design that I've seen so far. I would love to see similar functionality in Antetype.
