Q: Since this is built on React Native, is it possible to build pages using Hyperview and then supplement them with stateful UI component trees using common RN libraries (eg, Redux)? Like, mix approaches?
It is possible. We've built apps this way (integrating Hyperview into an existing RN app). With custom behaviors, you can have actions in Hyperview screens trigger Redux actions: https://hyperview.org/docs/reference_custom_behaviors
