  - Measure power consumption and improve battery life
  - Improve documentation, take better pictures and video than mine
  - Improve the UI
  - Create companion app for multiple OSes (Linux, Android, IoS) and platforms (desktop, ARM, mobile). Do not forget the other devices from Pine64 like [the Pinephone](https://www.pine64.org/pinephone/) and the [Pinebook Pro](https://www.pine64.org/pinebook-pro/).

 The schematic of your board (the Pinetime schematics in this case) will also be very important, as you'll need to know how the LCD controller is physically connected to the MCU.
 
-How to read the datasheet? I recommand to read it from the beginning to the end (no joke) at least once. You certainly do not need to read everything in details, but it's good to know what information is available and where in the document. It'll be very useful during the developpment phase.
