(A) either export option for an 'auto-generated spec' that we can send to the engineers OR (B) a 'view only' license (like what Figma has) so that engineers can just open the prototypes and inspect animations. This would save so much time on spec'ing motion and behaviour

It would be amazing if I could use a JSON file to populate reusable components with unique data/images instead of having to create each one as a one-off.

While moving objects around, they are often placed on subpixels (not sure if that's the term but X = 280.19; Y = 704.83). That means I have to go in and manually fix in all the numbers before I start adding triggers because I'd like to have triggers detect on whole pixels. If there was a 'snap to pixel' button, it'd take that manual step of rounding up/down the numbers myself every time I position something.

Being able to nest components inside components, allowing creation of more complex components

Similar to Adobe XD functionality, a checkbox for containers or shapes that makes everything underneath it blurred.

It would be great to being able to access to user live location through the phone GPS. Being able to ping the GPS, knowing user location in real time and being able to display it on a map (Google or Mapbox) would be a game changer

While i don't need bidirectional sync, it would be very helpful to update the design. Often you just start with mockups or just do little adjustments on the way. It's impossible to do adjust things a second time only for the prototype. So like Flowtools like Overflow it would be nice to update a design without the interactions.
