Right now, your prototype looks very much like a prototype—an e-panel module connected with a bunch of wires to an Arduino MKR WiFi 1010. In Chapter 8, Presenting Your Own Prototype, you will get an idea of how to present it in a nicer way. The first step, which does not consume too much time, is to create a case using thick paper or cardboard. Typically you would measure the dimensions of your components and build a custom case for it using paper/cardboard, a pencil, tape, and scissors.
Do you have some ideas about what modules/components you could add to it? Maybe a button to reset the text? When your e-paper to-do device reminds you to take out the trash and you prepare to leave the flat, it would be nice to just press a physical button to clear the display instead of getting out your smartphone and sending an MQTT message to clear...
