Minimalistic Email UI Exploration

I wanted to explore some ideas on minimalistic thumb-area-only UI, and if I can create a more immersive email experience.

I had this idea of an auto-hiding widget that would also sort of morph into different states - a nav drawer, an action bar (on selecting a list entry), etc. I haven't done any user testing or anything like that, but the prototype feels neat.

I like the ProtonMail service, so I created this 'fan-art' prototype! Also, they are hiring, so check them out!

The prototype was created using Framer: https://framer.cloud/NJfFq
